Geography 5 Field Trip

Field Trip OneMormon Rocks
Mormon Rocks was formed due to erosion that happened overtime through rain and snow. This is how Mormon rocks gets its layers. The reason for its holes is because there used to be large rocks inside and they fell out. Mormon Rocks is made from sandstone. It lies along the San Andreas Rift Zone.
Mormon Rocks Granular Structure
The granular structure if Mormon Rocks is made from sandstone. As shown in the photo we can see little rocks (some larger than others). The reason for its holes is because there were other larger rocks inside which fell off.
Mormon RocksSan Andreas Rift Zone
This is the San Andreas Rift Zone. This is here because the Pacific plate is moving north and the North American plate is moving South. This is what we call a transform fault plate boundary.
San Andreas Rift Zone
Cinder HillCinder Hill is a Cinder Cone Volcano. This Particular volcano last erupted some 500 years ago. Its remains contain basalt which gives it its red color. There are rocks here that have been thrown out of the volcano called scoria which contain tiny holes due to volcanic gasses.
Cinder HillLava Flows
Lava flows
The lava flows are made of basalt which is a rock that has lots of little holes in it due to the heat from the volcano. All the gasses get trapped inside the lava making little bubbles and when the lava turns to stone we get these little holes. The lava flows not only came from Cinder cone but from the chain of volcanoes called Coso Mountain Range to the East.
Lava flow wall
Fossil FallsStream Bed
This stream bed is called fossil falls. This place was home to the Native Americans and they used to thrive here with its raging waters. The water has dried now only leaving us with these rocks that have been softened and smoothed out by the water that used to pass through here.
Fossil FallsFossil Falls was created by the lava flows that came from cinder hill and other neighboring volcanoes. The Owens River that ran through here Smoothed and polished the rocks. This is a waterfall that drops down to forty feet.
Fossil Falls Metate Holes
These metate holes were made from the holes that are caused from the volcanic gasses and from the water that ran through here which was the Owens River. This stone is called basalt.
Fossil Falls Obsidian Flakes
These obsidian flakes litter the ground near the volcano because they were ejected from the volcano at the time of eruption. These are made of obsidian which is a type of glass. It is very smooth and the Native Americans used to use this glass for arrowheads.
Fossil Falls Petroglyph
This petroglyph which is a drawing made by the Native Americans telling a story shows us a big horned sheep that is now endangered. Perhaps they were thriving long ago. The bottom picture might be that of a shaman which is a leader or a medicine man. This painting is proof that the natives used to live here and they tell us their story through this petroglyph.
Fossil FallsHouse Rings
These house rings are another piece of evidence that show us how the Native Americans used to live. They would build their huts/teepee’s around these rocks called house rings. The entrance of their home would face east facing the rising sun.
Field Trip TwoMt. Whitney Interagency Visitors Center
Mt. WhitneyElevation 3686.2 ft.
This is Mt. Whitney it was great importance because it is part of the Sierra Nevadas. They cast a rain shadow over the Inyo-White Mountains which gives them a lack of vegetation, rainfall and snow.
Mt. WhitneyOrographic Effect
As we can see there a great difference between Mt. Whitney’s tall pointy peaks and the Inyo’s and their brown dull hills. The Inyo-White Mountains lack vegetation because Mt. Whitney casts a rain shadow over the Inyo-White Mountains which reduces the amount of rain they get hence the lack of vegetation.

Diaz Lake
This lake was caused by a huge earthquake the earth cracked and made a big hole. This is how Diaz Lake was formed.
Manzanar
Guard Shack and Plaques
Housing for the Japanese at the camp
The Japanese were placed here for about 5 years. They had them arrive and build everything themselves. They tore them apart from their families and they did this because the Americans were afraid of what had happened at Pearl Harbor and were just doing this to protect themselves from the Japanese that already lived here.
Manzanar
This planter has graffiti from the Japanese. They marked the dates when they stayed
here.
Mammoth Rest AreaBeetle Bark Infestation
The beetle bark infested forest has beetles that have gone inside the bark of these trees and destroyed them causing them to become weak and break.
These marks on this piece of bark indicate the damage that has been caused by the beetle.
Mono Lake and Islands
Mono lake has two islands one of them is a volcano. The volcanic lava has formed this volcano under water and has caused it to get to the surface and create an island.
Volcanic Island
Regular Island
Mono Lake Former Shorelines
Mono Lake has former shorelines. The evidence is that we can see an exposed shoreline, the vegetation is different on the outskirts of the lake compared to the actual shoreline we see now, and the tufas are out of the water indication of former water levels.
Different vegetation, larger bushes on the outskirts, smaller plants as you approach the lake.
Exposed Shoreline
Mono Lake Former Shore Lines
Tufa’s are out of water and the vegetation is different. Exposed tufas
Different Vegetation
Mono LakeTufa Formations
Calcium Carbonate
Limestone and Calcium Carbonate forms in the water bubbling from under the lake along the fault, the two mix and form tufa.
Bloody Canyon
Glaciated Valley
Moraine
When there is an avalanche a moraine is created. Sometimes due to a large earthquake.
Convict Lake
Convict Lake was created by a moraine. A moraine can be caused by an earthquake causing rocks to create a pathway or a type of space that can be filled with water like Convict Lake.
Convict LakeLateral and Terminal Moraine
Lateral and Terminal Moraine are created by avalanche and then lake
is formed.
Convict LakeOldest Rock Formations
Oldest rock formations are formed at the peak because everything gets pushed up. The youngest part of earth is towards the bottom.
Keoughs Hot SpringsThe stream is hot because there is a crack in the ground that reaches down to the depths of earth and as it is known the closer you get to the center of the earth the hotter it gets so it is hot because the water reaches down to where it is hot. The higher you go up the creek the hotter it gets.

Eastern California Museum
Eastern California Museum
I found it Interesting how many of these shoppes and houses are still in pretty good condition. I liked it so much that me and Eddie decided to reinact the American Gothic Painting since he happened to find a pitchfork!
Eastern California Museum
I also found this printing press! I found it to be very interesting because I didn’t really know how huge these things were!!! I’m glad I was able to see one in person!
Extra CreditCucamonga alluvial fan
Alluvial fans are created when water passes down a hill or mountain and it creates a fan shape.

Extra CreditSolar Power Plant
Extra CreditDoppler Radar Tower
Extra CreditL.A. Aqueduct
Extra Credit Mine Tailings
These mine shafts were used by the early settlers and they used to mine for gold. The pile of dirt on the right is made of minerals which gives them their pretty colors. The red is made from iron, green from copper, and yellow from sulfur.
Extra CreditGarlock fault
Extra CreditOwens Dry Lake
Owens Lake is dry because L.A. took all of its water!!! The townspeople destroyed their aqueduct lots of
times. L.A. took the water from streams that led to it since this was a salt water lake.
Extra CreditSETI Towers
SETI Towers are used to detect
extraterrestrial life!!!
Extra CreditCrowley Lake
Extra CreditManzanar Housing for Japanese
