Three Tiers of California Desert Vegetation
This picture shows the three
tiers of vegetation in a
California Desert
1. The Joshua Tree (In red) is
the top tier.
2. The creosote (In blue) is
the middle tier. This is the
shrubs.
3. The burroweed grass (In
violet) is the bottom tier.
Solar Power Plant
This picture shows the solar
power plant at the intersection of
the 395 Highway and the 58
Highway in California.
Doppler Radar Station
The Doppler Radar Station is
used for weather prediction from
Satellite Imagery.
Mine Tailings
These piles of debris are formed
from mining near Red Mountain
by the Rand Mining District.
Harper Dry Lake
Dry river beds in the Mojave
Desert.
Garlock Fault
Fault in the Mojave Desert.
SETI Towers
The SETI Towers are satellite
dishes that are searching for
messages from space. SETI
stands for Search for
ExtraTerrestrial Life.
Stratus and Nimbus Clouds
The weather was changing while
were at Mono Lake. This is
seem by the Stratus clouds
(Circled in blue) and the Nimbus
clouds. (Circled in red)
Geese in Bishop
For a stop in Bishop, we parked
near a park with a stream that
had geese and Mallards in it.
Mallards in Bishop
Here is a better picture of the
stream in Bishop, with only
Mallards.
1st Field Trip
Mormon Rocks
Mormon Rocks Formation
Mormon Rocks Structure
The granular structure of the
Mormon Rocks sandstone shows
that it is comprised of
sedimentary rock over time.
Mormon Rocks Stream Bed
This stream bed, in Mormon Rocks, is part of the San Andreas Rift Zone that separates the Pacific plate and the North American plate.
Cinder Hill
Cinder Hill
Cinder Hill is a cinder cone volcano.
Lava Flow
The black rock is basalt. These formations are from lava cooling quickly as it flowed out of a volcano.
Fossil Falls
Owens Riverbed
Owens River is a dry riverbed near fossil falls.
Fossil Falls
Fossil Falls is a dry waterfall that was part of the Owens River.
Metate Holes
Metate Holes are holes in the large rocks near waterfalls and rapids. They are created by small pebbles revolving very fast in the same place from running water.
Obsidian Flakes
These Obsidian Flakes were put here by Native Americans for the making of arrowheads and other tools. They would travel to nearby volcanoes to collect large pieces of obsidian and then shape the obsidian nearer to home.
Petroglyph
Drawn by Native Americans on rocks
House Ring
This ring of rocks is a house ring. The Native Americans would move seasonally. They would leave rings of rocks to mark the place they dwelt, so when they moved back, they could reestablish the same spot.
2nd Field Trip
Diaz Lake
Lone Pine Fault
The Lone Pine Fault is next to Diaz Lake. The hills in the background are the Alabama Hills of California.
Diaz Lake
Diaz Lake is a sag pond. It was created from the shifts of the tectonic plates from the nearby Lone Pine Fault. Earthquakes made the ground uneven and the water settled to the lowest point in the area.
Mount Whitney
Mount Whitney
This is Mount Whitney. We did not go to the Mt. Whitney Interagency Visitor’s Center.
Keoughs Hot Springs
Keoughs Hot Springs
Keoughs Hot Springs are hot springs created from seismic activity. Earthquakes cause cracks in the Earth’s surface that water seeps through until it gets hot. Heat rises bringing warm water up to the surface.
Keoughs Hot Springs
This is as close as I could get to the actual spring from the ground.
Glaciated Valleys
These glaciated valleys were created from glaciers sliding down the Mountains. The low Hills are the sediments that the glaciers pushed down. These are called moraines.
Mono Lake
Nearby Forest Fire
At Mono Lake, we saw smoke from a nearby forest fire. It is unclear if it was a controlled blaze or a wild fire.
Volcanoes Near Mono Lake
The mountains around Mono Lake are actually volcanoes that have not recently erupted.
Neget and Pehoa
The island circled in red is Pehoa. The one in blue is Neget. They are both volcanoes form in the center of the Mono Lake.
Tufa Formations
Formed where freshwater streams empties into a saltwater lake, these mineral formations, called tufa grow upward from the bottom of the lake. In most cases the tufa stays underwater, but because of Mono Lakes receding shoreline, these formations become completely exposed.
Current Shoreline
The Current Shoreline of Mono Lake.
1963 Shoreline Marker
Still hundreds of feet from the current shoreline of Mono Lake, is this marker showing the shoreline in 1963. Receding waters from the nearby Los Angeles aqueduct avert tributary streams away from Mono Lake causing the lake to shrink.
Old Mono Lake Size
Lines on the nearby hills, show the shoreline of Mono Lake hundreds of years ago.
Duck in Mono Lake
Wood ducks feed on brine Shrimp in Mono Lake.
Whigens in Mono Lake
Whigens are another bird species that feed on brine Shrimp in Mono Lake.
Cormorant in Mono Lake
Cormorants are another bird species that feed on brine Shrimp in Mono Lake.
Panum Crater
Panum Crater
Panum Crater is a Volcano that has a smaller volcano inside of it.This is the valley of Panum Crater.
1981 Burn Area
In 1981 there was a wildfire that swept the area near Panum Crater. The lighter vegetation is were plants have grown back since the fire.
New Burn Area
A more recent wild fire shows the charred remains of native plants
June Lake Loop
Grant Lake
Grant Lake is a man made lake, red by Rush Creek. When the Los Angeles aqueduct was being built, a dam was built to control water flow into the aqueduct. This dam caused water to gather, causing this lake to form.
Lateral Moraines
Across Grant Lake you can see lateral moraines caused from the glacial settlement.
Waterfall
Waterfall near silver lake.
Silver Lake
Silver Lake
Mallard in Silver Lake
This mallard was found swimming in Silver Lake.
Convict Lake
Convict Lake is a cirque, which is a lake caused by glaciers
Sevehah Cliffs
The Sevehah Cliffs are the Oldest Rocks in North America.
Bird Near Convict Lake
This bird in flight is probably a male Phainopepla. I tried to get a picture walking in the parking lot, but the bird was skittish.
Eastern Sierra Museum
Old Map of Bishop Area
At the Eastern Sierra Museum, I saw this map the museum was trying to preserve. It was displayed in the local drugstore in the 1950s. I am amazed at the pictures in the map. It was probably for tourists to see nearby interesting places to visit.
Manzanar
Manzanar
Manzanar was a relocation camp that the United States used to keep Japanese Americans in, during World War II. Now there is barely anything left, except rocks and foundations of old buildings. After the war, people used the wood and other materials to build buildings in nearby towns.
Plaques
The Japanese had to build their own buildings at the camp. Many would put there names in the concrete foundations or like this in what was probably a fountain in the main square.
Field Question 1Mormon Rocks is a tilted fault block. As the Pacific Plate pushes against the North American Plate
at the San Andreas Fault the rocks break and the rocks jut upward. In this instant Geologists can determine important information through the layers of rock exposed through the fault line. Some of the information that can be determined are annual rainfall averages, seismic activity and biome information.
Mormon Rocks is sedimentary rock around the San Andreas Fault. The San Andreas is the key point to the seismic activity in Southern California, and the pressure is building in this area. It is also were we can see information to the Earth beneath us through the Layers exposed.
Field Question 2At Cinder Hill, I saw a cinder cone, lava flows, alluvial fans and other
volcanoes. Cinder Hill is a cinder cone type volcano. In the picture on the next page, the lava flow is the darker area at the side of the mountain, circled in red. The alluvial fan is circled in blue. The volcano is circled in green.
Near Fossil Falls, there were three evidences of former Native American habitation. First was the chips of obsidian on the ground. Native Americans would travel to volcanoes and collect obsidian, so they could make arrowheads and other tools. Second are the house rings. Native Americans would mark the spot of their homes, so when they returned from seasonal migration, they could resettle in the same spot. The third evidence is the petroglyphs drawn on the rocks.

Landforms Near Fossil Falls
The Volcano is green, the Lava Flow is red and the Alluvial Fan is blue.
Field Question 3The Sierra Nevada Mountains and the White Inyo Mountains look very different. The Sierra Nevada
Mountains are larger and have step U shaped valleys. The White Inyo Mountains are smaller and have more rolling V shaped mountains.
The Sierra Nevada Mountains are an older mountain range with moraines. The U shaped valleys are caused by the glaciers that weathered the mountains. The glaciers carved the valleys taking sediment down with them and the piles of sediment are the small rolling hills at the bottom of the mountains called moraines.
The White Inyo Mountains are younger and shorter than the Sierra Nevada Mountains. The White Inyo Mountains do not have as much glacier weathering, so the valleys have more of the V shape. There are also no real moraines where we were looking at them.
Field Questions 4Using the Analema on November 6, 2010, as we were visiting Mono Lake, the Subsolar Point
(Where the sun is directly 90 degrees overhead.) was at the latitude of about 16 degrees south. The Subsolar Point was in the Southern Hemisphere. Mono Lake is at a latitude of 38 degrees north. Therefore, adding the two latitudes together, because the latitudes are in separate hemispheres, the arc distance is 54 degrees. Subtracted from 90 the solar angle of the Sun at Lee Vining is 36 degrees. This means at the highest point of the day (the Zenith Point) the Sun is only 36 degrees up from the horizon in the south.
We also know from the Analema, on November 6 th, the Zenith Point is sixteen minutes fast. In other words the Sun hits it’s Zenith Angle of 36 degrees above the horizon at 11:44 AM.
Field Question 5At Panum Crater there are many landforms to see. Panum Crater itself is a composite volcano with a cinder cone
volcano inside. Neget and Pehoa are also small volcanoes inside Mono Lake. There are nearby mountains with moraines at the feet of them. In Mono Lake, you can see the tufa from Panum Crater.
Three evidences of former lake levels are first the lines on the nearby hills. This is seen in slide 48. The second evidence of former lake levels are the tufa. The are naturally formed underwater and only exposed by the receding shoreline. The third evidence is the sign put out of the 1963 shoreline.
