As practitioners of the earth sci-ences, we are all well aware of theever-changing environment around us.We understand that “time and tidewait for no man.” While that is trueintellectually, it is hard to accept on avisceral level. Change that makes ourlives interesting, that challenges us tokeep learning, that assures us the sunwill rise tomorrow, sometimes isunwelcome when it robs us of thefamiliar. This issue of Pennsylvania Geology is a bittersweet testimony tothat type of change.

Our profession has lost two practitioners of geology, Tom McElroyand John Way, two men who spent the best parts of their adult lives shar-ing their insights into geology. A brief memorial to each is containedwithin these pages. I hope that those of you who knew them will remem-ber them fondly and smile from time to time at some good recollection;those of you who did not know them are unfortunate. Perhaps the bestthing one can say is to enjoy those around you, no matter their professionor position. Everyone brings a story to the table; something can belearned from everyone if you listen. These were two gentlemen worth lis-tening to.

Stellar Geologist—Dean B. McLaughlin

Stuart O. ReesePennsylvania Geological Survey

The Pennsylvania Geological Survey has a long history of employing exceptional geologists whohave served the state with their science skills and abilities to synthesize geologic data into practicalreports. In addition, the Survey has been assisted over the years by superb cooperating scientists whohelped map the geology of the commonwealth. Dean B. McLaughlin (Figure 1), one such field geolo-gist, last worked at the Survey more than 45 years ago.

Two-Sport Star

What’s unusual about Dean McLaughlin is that he was nota geologist by training. His main vocational field was stellarspectroscopy, which is a fancy term for the study of stars, plan-ets, and other astronomical bodies using the compositions andproperties of light waves. McLaughlin was a well-known Uni-versity of Michigan astronomer and author of the 1961 textbookIntroduction to Astronomy. This astronomy text stands out togeologists with its many references to geological processes. It’sobvious that geology was his favorite “hobby.” Survey geologistJohn Barnes remembers his surprise the first time he heard thatMcLaughlin, author of the textbook John had recently used forhis college astronomy class, had mapped geology for his newemployer. At last, John had an explanation for why there were somany geology photographs in the astronomy text.

Dean B. McLaughlin was the son of Michael and CeliaMcLaughlin and was born in Brooklyn, N.Y., in 1901. He spentmost of his academic career in the Department of Astronomy atthe University of Michigan in Ann Arbor, first as a student whoearned B.A., M.S., and Ph.D. degrees (1919–27), and then invarious capacities as an instructor from 1922 to 1924 and from1927 until his death in 1965 (Hockey, 2007). He also spent threeyears (1924–27) teaching at Swarthmore College in DelawareCounty, Pa. There, he became interested in the Triassic redbeds

that were located about 15 miles north of Swarthmore (Hoskins and Jordan, 1999). Beginning in 1951,he did cooperative work for the Pennsylvania Geological Survey and devoted significant time to map-ping Mesozoic sedimentary rocks in southeastern Pennsylvania.

Dr. Charles Cowley, University of Michigan Astronomy Professor Emeritus, remembers speakingto an old professor from the geology department (Eberhardt Heinrich, Emeritus Professor of Mineral-ogy and of Geological Sciences) who told him that McLaughlin was as good a geologist as he was anastronomer. Retired Pennsylvania State Geologist Don Hoskins, who started at the Survey in 1956,remembered him, but said, “You didn’t see him much—he was always out in the field.”

Take Note

I first came across McLaughlin’s work as I initiated research for a new assignment: reexaminingthe bedrock geology of the Middletown 7.5-minute topographic quadrangle. I first confused McLaugh-lin’s name with that of another bureau geologist, David B. MacLachlan, who served as a staff geologistfrom the 1960s to 1996. Both names, D. B. McLaughlin and D. B. MacLachlan, show up on geologicmaps of areas in central and southeastern Pennsylvania. One publication, Atlas Report 177d, Geologyand Mineral Resources of the Sinking Spring Quadrangle, Berks and Lancaster Counties, Pennsylvania(MacLachlan, Buckwalter, and McLaughlin, 1975), bears both names.

I am fortunate to see firsthand McLaughlin’s field observa-tions that fed into geologic maps and reports, in that I haveaccess to his field notebooks (Figure 2). Through McLaughlin’sfield notes, I have become acquainted with his work. He and oth-ers determined that the bedrock of the Middletown quadrangle isdominated by Triassic-age rocks, underlying about 94 percent ofthe quadrangle. I am using a new framework of contemporarygeological studies, concepts, and tools such as lidar coverage oftopography at 2-foot contour intervals. This framework allows afresh look at the mapping that was done 50 to 60 years ago.

Reach for the Stars and Keep Your Feet on the Ground

McLaughlin had a prominent role in astronomy that earnedhim an entry in The Biographical Encyclopedia of Astronomers(Hockey, 2007). It is noted that McLaughlin “participated in thediscovery that stars in general rotate like the Sun and that mem-bers of close binary systems are often rapid rotators” (Hockey,2007, p. 759). The “Rossiter-McLaughlin effect” was namedafter a discovery that he and older colleague Richard Rossitermade regarding the way light behaves as companion stars inclose binary systems transit or eclipse one another. He made animpact in astronomy and has craters named after him on both themoon and Mars.

His geologic interests were intertwined with the heavens. In the 1950s, he presented a series ofpapers at geological and astronomical society meetings that postulated that Mars was actively volcanic(for example, McLaughlin, 1956). This argument attracted the negative comments of the astronomerGerard Kuiper of Kuiper belt fame. McLaughlin argued that the patterns of dark sediments were in factvolcanic ash recently blown out of volcanic vents. More than 50 years later, the jury is still out onwhether Mars is in fact “actively volcanic.” However, in 2010, NASA released new data gathered bythe Phoenix Mars Lander that provided additional evidence “that volcanic activity has persisted on theRed Planet into geologically recent times, several million years ago” (NASA, 2010). Research on Marsmay ultimately tell the story of how recent is “recent,” but McLaughlin was at least more right thanwrong on this topic.

Triassic Trek

In the meantime, through a work agreement with the Survey, McLaughlin began in the early1950s to map in the Triassic basin (Figure 3). He spent most of the next 15 years doing fieldwork

Pennsylvania Geology Spring 2012

Figure 2. One of Dean B. McLaughlin’sfield books from 1962–64.

during summer recess, semester breaks, and at other opportune times. This was not introductory workwith the Triassic rocks. As early as 1933 he had authored a paper on the Triassic Brunswick Formation(McLaughlin, 1933). In 1939, he wrote a 15-page article on “a great alluvial fan in the Triassic ofPennsylvania” (McLaughlin, 1939).

His field books show him mapping seven days a week in the summer, even when days hit 100°F.Here is a July 1, 1963, field book entry:

Temperature reached 101 according to report—humidity very high too

On July 3, 1963, even he had his limits, and he was nearly 62 years old, writing:

Too hot to continue. Went to Survey office in Harrisburg & worked on MS [manuscript] copy ofHummelstown quad

The bedrock geology of the Mesozoic had been mapped at 1:62,500 scale or smaller in the 1920sand 1930s, mostly by combinations of George Stose, Anna Jonas (whose name changed to Stose aftershe married George Stose in 1938), and Florence Bascom. Starting in the 1920s, McLaughlin began his study of Triassic rocks. In the 1950s, his Survey work provided detailed and systematic mapping at 1:24,000 scale. His field area extended from the Susquehanna River in Dauphin County to theDelaware River in Bucks County. He eventually covered more than 1,000 square miles of the Gettysburg and Newark basins east of the Susquehanna River.

By 1964–65, he was working in the Middletown and Elizabethtown areas of Dauphin and Lan-caster Counties. His work was used in numerous publications, and current geologic maps that cover the Gettysburg and Newark basins reference his work as follows: “file manuscript maps by D. B.McLaughlin.”

In 1966, the bureau released General Geology Report 43—Provenance, Dispersal, and Deposi-tional Environments of Triassic Sediments in the Newark-Gettysburg Basin (Glaeser, 1966). GeologistJ. Douglas Glaeser began his 168-page report with a tribute to Dean McLaughlin, as follows:

This volume is dedicated to Dean McLaughlin, astronomer and geologist. Without his intensive work car-ried out over the last twenty-five years in detailed field mapping of the Triassic Newark-Gettysburg basin,a study of the kind presented here would have been impossible. The writer has benefited from numerousdiscussions with Dr. McLaughlin and many of the ideas in this paper are reflections of his thinking.

Starry Notes

McLaughlin’s field books survived the tropical storm Agnes flood of 1972 that destroyed the Sur-vey library. The notebooks are systematic descriptive fare of mostly red Triassic rocks, yet in the mar-gins and open spaces there occasionally appear some comments that testify to Dr. McLaughlin’s otherinterest (some made late in the evening).

The following is an April 9, 1962, entry:

L & L Motel, Monday evening. Saw Comet Seki-Lines, several (7 or 8) degrees N of Venus. Tail 8or 10°—car lights interfering. Brilliant nucleus 3 d mag or so.

This is in reference to the comet newly discovered almost simultaneously by Americanastronomer Richard Lines in Arizona and Japanese astronomer Tsutomu Seki in Kochi, Japan, in Feb-ruary 1962 (Porter, 1963).

An April 7, 1963, entry reads:

April 7-8 at 12:15 am EST = Apr 8, 5:15 GCT Nova est mag 6.8

A June 21, 1963, entry is:

Nova Herculis 1963. June 22.08 UT 7.7? easily seen, but did not see comp * 7.9

These entries refer to a nova—a starthat rapidly increases in brightness, typi-cally because of an accretion of matterfrom a companion star in a binary system(Figure 4). “Did not see comp * 7.9”means that he could not see a comparisonstar of the nova to estimate its brightness.The nova Herculis was discovered inFebruary 1963 by American and Swedishastronomers. McLaughlin was one of theastronomers who measured the nova (VanGenderen, 1964).

While finishing up his last quadran-gles, he also submitted a paper to TheAstrophysical Journal on August 16,1965, entitled The Be Spectrum Variable105 Tauri. This was a paper regarding theberyllium emissions of a star named 105Tauri (McLaughlin, 1966).

Last Days in the Field

McLaughlin’s last field day for the Survey was Friday, May 21, 1965, a day he spent mapping inthe Elizabethtown quadrangle. From there he traveled eastward where he was one of the leaders on aweekend field trip conducted by the Philadelphia Geological Society. But all was not well. That week-end, he wrote two unusual personal notes in his field book:

1965 May 22

Field trip of Phila. Geol. Soc.

—Laura McLaughlin went along. [Laura was his wife of 38 years.]

—I had some pain but slept without using pill. Sunday May 23. Some severe pain, especially inevening at L&L Motel. 2 pills 4 h apart, only partial relief.

Later in June he returned to the Survey but again he did not feel well and did not make any morefield book entries. He drove back to Michigan for an anticipated hospital stay. Then-Assistant StateGeologist Alan Geyer wrote, “We at the Survey were worried about you driving home to Ann Arborwhile not feeling well.”

Despite his ill health, McLaughlin continued that summer to labor on geologic reports based onhis field mapping, while also doing astronomical work. As usual, once the school year started, hewould resume his full-time role as an astronomy professor.

So Much to Do. . .

McLaughlin wasn’t satisfied with some areas of his geologic maps. His plan was to take a year-long sabbatical from the University of Michigan so that he could devote more time to geologic map-ping.

McLaughlin’s name would probably be more familiar to those who use Survey publications had itnot been for his untimely death in December 1965. His foundational work in Mesozoic rocks is refer-enced in numerous publications that covered southeastern Pennsylvania, and his name is on five differ-ent Survey publications as a coauthor, even an atlas report released 10 years after his death.

His appreciation and love of geology can be seen in the way he ended his argument in a paperregarding the volcanic controversy of Mars. He said, “This does not imply that a geologist’s interpreta-tion will surely be correct. It does mean that without the application of geological thinking, there isscant hope of ever solving the problem.”

The University of Michigan (1965) memoir contained this about McLaughlin: “He will long beremembered for the perfection of his scientific studies and will long be beloved for his unstinting gen-erosity. . .whereby he made his knowledge and talents available to students, colleagues, and the world-wide community of astronomers.”

The Survey was fortunate to tap into his geologic passion for a number of years, though it wasbasically McLaughlin’s “spare time.”

In 1965, in his last letter back to the Survey from Michigan, McLaughlin lamented that his workon the Elizabethtown quadrangle was in “such a sloppy state. . .” His last words in his letter were,“time is running short!” In a letter dated the next day that crossed McLaughlin’s last letter in the mail,then-Assistant State Geologist Alan Geyer was not of the same mind: “You have done the impossible—you have completed the mapping of the Triassic.” McLaughlin’s health complications from prostatecancer were severe; he died on December 8, 1965, in Ann Arbor, Michigan, at the age of 64.

Although the field of astronomy fittingly has a claim upon the work of Dean B. McLaughlin, hisgeologic work in Pennsylvania was impressive in its own right. He was truly a “stellar geologist.”

IN MEMORIAM

Thomas A. McElroy1949—2012

On February 8, 2012, we lost one of our former Survey colleagues, Thomas A. McElroy, to cancerat age 62. Tom passed away at home that evening after a battle with the disease that lasted for severalyears. He is survived by his wife, Deirdre (Dede).

Tom was born in Olean, N.Y. He served in the U.S. Air Force, including a tour of duty in Viet-nam. After returning home with an honorable discharge from the military, Tom obtained a B.S. degreein geology from Harpur College of the State University of New York at Binghamton and an M.S.degree in geology from the University of Massachusetts at Amherst.

Tom came to the Survey in 1980 and worked for most of the time until his retirement in October2010 as a hydrogeologist. He completed a number of major groundwater investigations and reports inthe Allegheny Mountain section of the Appalachian Plateaus physiographic province. His countywidesummaries for Fayette (1988), Cambria (1998), and Somerset (2001) Counties were published by thebureau. Tom also coauthored the county summaries of Indiana County (Williams and McElroy, 1991,

1997), which were pub-lished by the U.S. Geolog-ical Survey. In all of thesereports, Tom not onlycharacterized the hydroge-ology of the counties, buthe also compiled andupdated the mapping, withothers, of the bedrockgeology. The SomersetCounty report included acompletely new geologicmap. For this project, Tomwas responsible for map-ping the MississippianPeriod rocks.

Tom’s last hydro-geologic project was tohelp produce a statisticalcompilation of the hydro-geologic and well-construction characteristicsof the geologic units of thestate geologic map, and hewas a coauthor of theresulting report, Water

This 155-foot-deep cut crosses the axis of the second-orderBlue Mountain anticline and displays very complex structures. The location was Stop 1,co-led by Tom, of the 2007 Field Conference of Pennsylvania Geologists. Photographby Gary M. Fleeger.

Resource Report 69. For that project, Tom reviewed each of the approximately 50,000 well recordsused to determine the appropriate geologic formation and physiographic section in preparation for thestatistical analysis, probably his earliest foray into the use of GIS as an analytical tool.

After having done bedrock geologic mapping as part of his hydrogeological studies, it was not amajor change when in his last few years with the Survey, he transferred to the Mapping Division. Hefirst mapped the Great Bend 7.5-minute quadrangle in northeastern Pennsylvania (2002). Then hebegan mapping the complexly folded and faulted bedrock in the Ridge and Valley province, in collabo-ration with retired State Geologist Don Hoskins. Together, with Tom as principal geologist, they pre-pared new detailed bedrock geologic maps for a number of topographic quadrangles in the Ridge andValley province of central Pennsylvania—Lewistown (2004), Belleville (2005), Allensville (2007),Newton Hamilton (2008), McVeytown (2010), and McCoysville (2011). Each was published as a digi-tal report and full-scale map.

As a result of their mapping work, Tom and Don organized and led the 72nd Annual Field Con-ference of Pennsylvania Geologists in 2007, Geologic Mapping—“Walkabouts” in central Pennsylva-nia—1st-to-5th-Order Appalachian Mountain Folds; Folded Thrusts; Ordovician and Silurian Carbon-ates; Silurian Quartzites and Sandstones (Harper, 2007).

Tom’s mapping in both the Plateaus and the Ridge and Valley provinces resulted in articles inPennsylvania Geology highlighting interesting and/or rare features that he discovered. Notable of thesewas Tom’s article on recently exposed rocks on the west side of Lewistown, whose complicated geol-ogy led him to denote the area as “Oz” (McElroy, 2006).

Tom was also a long-time participant in the annual Field Conference of Pennsylvania Geologists.In addition to being a co-leader at the 2007 conference, he also co-led trips in 1993 (Somerset County)and 2002 (Tunkhannock). As a volunteer as well as a participant, he helped with the logistics of thetrips.

Tom retired in October 2010, partly to concentrate on his health issues. He continued to partici-pate in geologic activities until his health no longer permitted it. All of us who knew and worked withTom miss his presence in our ranks.

IN MEMORIAM

John H. Way1943—2012

John H. Way, a former staff geologist at the Pennsylvania Geological Survey and later a professorof geology at Lock Haven University, died on February 21, 2012, in Williamsport following a brief ill-ness. He joined our staff in 1971 and stayed for 15 years, making lasting contributions both as a fieldgeologist and as a geological editor, before accepting a position on the faculty at Lock Haven Univer-sity (LHU) in 1986.

John was born in Philadelphia in 1943 and grew up in the nearby community of Yeadon. His loveof nature and geology was aroused early during visits to the Delaware County Institute of Science inMedia, Pa. There, under the mentorship of curator Harold W. Arndt, John developed an interest in min-eralogy and geology. In addition to unique specimens which John was able to view there, John wasinspired by Harold’s stories of his field experiences with Sam W. Gordon’s mineral collecting excur-sions in Pennsylvania, on which Harold had been the unofficial photographer. John started his own col-lection, and some of his favorite mineral-collecting areas are believed to have been Bancroft, Ontario;Herkimer, N.Y.; and the Keystone Trappe rock quarry at Cornog, Chester County, Pa.

John majored in geology at Franklin and Marshall College and earned an A.B. degree in 1965, followed by an M.S. degree in 1967 from the University of Pennsylvania and a Ph.D. in 1972 fromRensselaer Polytechnic Institute in Troy, N.Y. His master’s degree research was a study of the sedimen-tary rocks that preserve aCarboniferous fossil forestthat is exposed in cliffs alongthe Bay of Fundy near Jog-gins, Nova Scotia. His doc-toral research was a study ofthe depositional environmentand the potassium, uraniumand thorium content of Mid-dle and Upper Devonianrocks in the Catskill Moun-tains of New York. Whilestudying in Troy he metRoberta (Bobbie) Seibert,who became his wife of over40 years. John and Bobbieraised a daughter, Mary.

During his years at theSurvey, John was responsiblefor completing several majorpublications, most notably amajor study of the geology of

the Altoona area, Geology and Mineral Resources of the Blandburg, Tipton, Altoona, and BellwoodQuadrangles, Blair, Cambria, Clearfield, and Centre Counties, Pennsylvania, published with Rodger T.Faill and Albert D. Glover as Atlas Report 86 in 1989, and another Atlas Report, 154cd, Geology andMineral Resources of the Washingtonville and Millville Quadrangles, Montour, Columbia, andNorthumberland Counties, Pennsylvania, published in 1993. But these reports barely tell the story ofJohn’s contributions here. He published many articles in Pennsylvania Geology and articles andabstracts in such outside publications as the Geological Society of America Abstracts with Programsand the guidebooks of the Field Conference of Pennsylvania Geologists, many coauthored with Surveycolleagues. Research topics included the Devonian Tioga Ash Beds and Bald Hill Bentonites (withRobert C. Smith, II, Samuel W. Berkheiser, and Mary K. Roden), 19th century iron-making at PineGrove Furnace, and the geology of South Mountain, Cumberland County. He also was a coauthor withThomas M. Berg, Michael K. McInerney, and David B. MacLachlan of the Survey’s Stratigraphic Cor-relation Chart of Pennsylvania (the “strat chart”).

John’s contributions to understanding the geology of the Ridge and Valley physiographic provinceand the economic geology of Pennsylvania were, and continue to be, significant. For example, the“strat chart” helps to define the framework of the Marcellus and Utica shale gas horizons. The Survey’sTioga Ash Bed study provided information on the base of the Marcellus play zone, but also delineatedthe correct direction of time transgression relative to lithologic facies. His careful work on volcanic ashbeds in the Middle and Upper Ordovician Union Furnace section helped establish that exposure asPennsylvania’s de facto type section for those beds and the basis of the bentonite nomenclature used inPennsylvania. His work on the lowermost Devonian Bald Hill Bentonites arose from the hypothesisthat termination of extended periods of carbonate deposition would be marked by volcanic ash beds.The ashes marking the end of the Silurian Wills Creek, Tonoloway, Keyser, Coeymans, and New Scot-land carbonates were found within an hour of searching in the transition to the lowermost DevonianMandata black shale at Bald Hill, Blair County. Weekend trips with family eventually extended theknown range of surface exposures of the Bald Hill Bentonites from near the Adirondack Mountains inNew York to McDowell, W. Va. In the process, the resulting detailed stratigraphic sections disproved athen-current assumption that punctuated aggradational cycles (PACs) were time-stratigraphic surfaces.

Despite John’s contributions that helped set the stage for the Marcellus gas development, he wasconcerned about its potential impact on the environment. John never profited from the Marcellus but,true to his principles, he volunteered countless hours to conservancies in central Pennsylvania seekingto protect watersheds.

John’s ability to write in a clear and interesting way for the nongeologist was amply demonstratedin his publication, Your Guide to the Geology of the Kings Gap Area, Cumberland County, Pennsylva-nia, published by the Survey in 1986. John also used his excellent communication and writing skills toadvantage during a three-year stint as a geologic editor at the Survey, from 1974 through 1977, whenhe helped convert a number of Survey publications from rough manuscripts to finished products. Heperformed a similar task as a volunteer, spending many hours of his personal time as the editor of the300-page book, The Mineralogy of Pennsylvania, 1966-1975, by Robert C. Smith, II, published by thePennsylvania Chapter of Friends of Mineralogy in 1978. To this same work, John contributed morethan 50 finely executed pen-and-ink sketches. From alloclasite to the back piece geologic time scale,all of the drawings were drafted by John.

At Lock Haven, John proved to be a very effective teacher, conveying to his students not only histechnical expertise, but his love of nature and excitement about the geological processes that shape theearth. John received the Teaching and Learning Center’s Peers Choice Award at LHU in 2004. Through

papers published while he was there, he made significant contributions to understanding the regionaland environmental geology of the Lock Haven and Williamsport areas. Among his contributions werefour field guidebooks covering the geology of the Erie, Gettysburg, South Mountain, and Johnstownareas. He also made one additional contribution to the Survey while teaching at LHU, authoring thechapter on the physiography of the Appalachian Mountain section for the Survey’s Geology of Pennsyl-vania compendium.

John’s enthusiasm and energy were infectious. Anyone who came into contact with him wasuplifted and energized by John’s positive outlook and the joy that he took in everything that he did.This extended well beyond his work to include his community, his church, and his family. Those of uswho were privileged to know and work with John are the better for it, and we will miss him.

NEW RELEASE

Nonfuel-Mineral Resources DirectoryGets a New Look

John H. BarnesPennsylvania Geological Survey

In 1965, the Pennsylvania Geological Survey issued the first edition of what was to become oneof its better-selling publications, The Directory of the Mineral Industry in Pennsylvania (O’Neill,1965). Because other compilations of sources of coal, oil, and natural gas already existed, this 85-pagedirectory was limited to nonfuel commodities such as limestone, sandstone, sand and gravel, shale, andslate. These commodities have many applications, including road building, other forms of construction,agricultural soil conditioning, dimension stone, and various industrial processes. The directory alsoincluded the state’s metal mines, none of which remain open today. The main purpose of this publica-tion was to provide a way of helping the consumers and producers of industrial minerals to find eachother.

The directory was enough of a success that a second edition containing updated information waspublished six years later (Hoover, 1971), and a third six years after that (O’Neill, 1977). Other editionsfollowed. Each time, attempts were made to make the directory easier to use. For the second edition, asimple map of the state was added that showed what commodities could be found in each county butthat did not show any exact locations. The third edition included a 1:500,000-scale two-color mapshowing the location of each operation. The fourth edition (Berkheiser and others, 1985) had a similarmap, and the fifth (Barnes, 1997) had smaller page-sized maps, each showing just a few counties at1:500,000, supplemented by smaller-scale maps showing the distribution of each commodity across thestate. Starting with Berkheiser and others (1985), the directory also carried a new title that was moreappropriate for its limited scope, Directory of the Nonfuel-Mineral Producers in Pennsylvania.

The 1997 edition of the directory was the first to be posted online as an Adobe Portable Docu-ment File (PDF). It was also the first to include map coordinates in the listings. As an experiment, theauthor used those data to create a rather simple digital mapping application that allowed users to view asearchable map that showed the locations of operations of interest. Viewing the map required the userto download and install special software, then download a specially formatted database and connect thesoftware to the database, so it was not particularly user-friendly.

Now, we are very pleased to announce that, in addition to an Adobe PDF tabulation, the newestedition of the directory (Barnes, 2011) can be accessed as a user-friendly mapping application that runson any modern computer that is equipped with a standard web browser (Figure 1). This was accom-plished through the efforts of Carrie Tropasso, the Survey’s newly hired Natural Resource Specialist,who brings experience in the development of mapping applications to us.

The map can be used to locate operations by product and/or lithology as well as by county or thename of the operation (Figures 2 and 3). Information about a selected operation can be displayed onthe screen, and driving directions to the quarry can be plotted (Figure 4). It is even possible to zoom infor a close look at the quarry (Figure 5).

We hope that the addition of this mapping application will improve the usability of the directory.Also, it is our hope that, now that the directory has been made into a fully digital product and formatshave been established, future updates of the data can be made in a more timely fashion.
