Trip One

Mormon Rocks

Mormon Rocks was formed by the North American plate moving southward and the pacific plate moving northward. While there is movement along the San Andrea’s fault it picks up the bottom of the stream bed and tilts it over. Mormon Rocks is a tilted fault block mountain at a 45 degree angle. Once it gets exposed to wind and water it erodes and it makes little and big layers.

Mormon Rocks has a granulated structure sand stone that is composed of sedimentary rock.

San Andreas Rift Zone and Stream Bed

The San Andreas fault is a strike slip type of fault in which two plates strike each other while moving in opposite directions. San Andrea’s

fault is located next to Mormon Rocks by the 15 Freeway.

Cinder Hill

Cinder Hill is a Volcano that erupted 500 years ago, and it’s a cinder cone volcano.

Lava Flows

The lava flows are made out of basaltic lava and are located in the mountains by Cinder Hill.

Fossil Falls

Fossil Falls was once a waterfall but all the water was diverted to the City of Los Angeles. Fossil Falls was formed by melt water

from the glaciers pooled into Owens River. The rivers course was diverted several times by volcanic activity. The falls were formed when the river was forced to divert its course over a basalt flow, polishing and reshaping the rock into a variety of unique shapes

and forms.

Metate Holes

The Metate holes on Fossil falls, were formed by the the river as it went over the basaltic rocks and brought smaller rocks that hit the are in a

circular motion that carved the holes.

Obsidian Flakes

Obsidian was found near the volcanoes, Native American that lived in the region created weapons, such as arrowheads from the obsidian. Some natives used to work on their weapons near the river which in turn left

small obsidian flakes in the river. Today the obsidian flakes found by the flat dry river bed are evidence of the natives existence.

Petroglyph

Petroglyphs are the images carved in the rock, which were created by

the Native American’s that once lived in the region. People interpret the

images in different ways.

House Rings

This house ring is

located on a high spot by the river and the natives

used to hang out in the area. The

rings were a foundation of a temporary

home.

Diaz Lake

Diaz lake was created in 1872 after an earthquake in which a plate went down, causing the formation the lake

Mt. Whitney reaches an elevation of

14,505ft. It is the tallest

mountain in the United

States.

Orographic Effect

The orographic effect occurs when moist air is pushed up the side of a mountain causing rain/snow on those mountains. As the air passes the

mountains, a rain shadow is created where the air warms and dries, leaving sparse amounts of precipitation.

Mono Lake

There are 3 different shorelines that can be seen in Mono lake. #3 is The ancient shoreline of Mono Lake which shows the size Mono Lake once was. #2

is the old shoreline after Los Angeles County diverted water to LA from the lake shrinking it from its original size. # 1 is the current shoreline which shows

Mono Lake’s size today.

Tufa

Tufa forms under Mono lake’s water. When fresh water springs rich in calcium bubble

up through the carbonate lake water react to form a calcium carbonate salt deposit called Tufa. This material continues to develop eventually forming vertical towers with spring water percolating up through and

around them.

Glaciated Valley and Moraine

Bloody Canyon - Glacier carved the U shaped which in turn created debris. A moraine forms along the sides of a glacier. As the glacier scrapes along, it tears off rock and soil from both sides of its path.

This material is deposited as moraine at the top of the glacier's edges.

Convict Lake

Convict Lake

In 1871, six inmates from

a Nevada prison

escaped here, they were

later caught and hanged by the lake,

giving Convict Lake its

name. The lake was

created from the glaciers.

As the glaciers melted, water

filled it in.

Oldest Rock Formation in The Sierras called Sevehah Cliffs.

Keoughs Hot Springs

The hot springs were created by an earthquake. While water flows through the cracks created by the earthquake, it is heated by the

volcanic activity that occurs underground and it is later pushed up as heat rises creating the hot spings.

ManzanarJapan’s attack on Pearl Harbor

December 7, 1941, led the United States into World War II. The attack intensified racial prejudices and led to fear of potential sabotage and espionage by Japanese Americans among some in the government,

military.

In fear of and attack by people of Japanese descent, the Manzanar

War Relocation center was created and it became the first of ten camps used to intern those of Japanese descent during World

War II.

Alluvial Fan

Cucamonga Alluvial Fan

An alluvial fan is a triangle-shaped deposit of gravel, sand, and even

smaller pieces of sediment, such as silt. This sediment is called alluvium. Alluvial fans are usually created as

flowing water interacts with mountains, hills, or the steep walls of

canyons.

Garlock Fault

The Garlock fault zone is one of the most obvious geologic features in southern California, clearly marking the

northern boundary of the area known as the Mojave Block as well as the southern ends of the Sierra Nevada and the

valleys of the westernmost Basin and Range province.

Erratic Boulder

One notable geologic feature is the perched

boulder, a glacier erratic next to the June Lake Fire Station. This boulder, a well-known landmark of the area, is 18 feet tall and weighs 150 tons. It

was carried and deposited by glacial action to its

present position
