Mormon Rocks- Trip #1 March 12, 2011 9:30- 11:00am
MORMON ROCKS “ROCK CANDY”1. Mormon Rocks Formation- When faults move (earthquakes or
seismic activity)bottom of stream bed is picked up and the rocks begin to form.
2. Stream Bed/ San Andreas Rift Zone- dried up river, and the clashing of san Bernardino and San Gabriel mountains because of tectonic plates **Train Passing through
Mormon Rock Formation
Stream bed/San Andreas rift Zone
Granular StructureWe can see the levels as they are formed in layers. Depending on the size of the layers and the amount and size of debris and rocks we are able to find out the amount of precipitation that year.
This is a very small but great example of how the giant Mormon rocks start to form. On this 10 ft wall. You can see the layers of sandstone start to build up and how high the water reaches at times in this dried up river during our rain season.
Thick layer =lots of rain
Water line of recent precipitation
Granular Structure & Mormon Rocks
Big wholes are formed because of the constant wind and because over time the rocks or giant boulders fall out.
Dried up waterfall
Small hole, where rock fell out
Water line of a recent waterfall, no longer there at time of field trip
Field Trip #2-April 8, 2011 Around noon
Stream Bed
Little Lake Dry stream bed Once called “Owens Little Lake “
Fossil Falls
40 FT. dry water fall Little Owens lake flowed through here once until the volcanic lava disturbed
and changed the direction of the streams.
Fossil Falls & Metate HolesFossil Falls
Metate Holes: were used by woman to crack the shells off nuts
and plant seeds.
Obsidian Flakes
Volcanic glass that was used to make arrowheads and other tools
Petro glyph
HousE rinGsThese rings were the foundation of their homes, which were covered with animal skins and grass and brush maybe.
Entrance to ring House Ring
Cinder HillCinder hill is a result of a violent eruption of trapped gases and molten material from a vent in the earths crust.
As the material cooled quite fast after air hit it, the hill was formed called Scoria
Lava Flows440,00 years ago the Coso Mountain range was an active chain of volcanoes that erupted a number of times . Slow flowing dark lava called Basalt.
Keoughs Hot SpringsThe hot springs are warm springs that are formed because of the faults that have left cracks and when the water gets in the cracks and comes up making the water warm
Hi!!
Mono Lake Committee Visitors CenterApril 9, 2011 around 11:00am
MONO LAKE COMMITTEE VISITORS CENTER
You can come here to learn some history about Mono Lake
MONO LAKE APRIL 9, 2011
AROUND NOON
Lake and Islands
Mono lake“Sea of the desert”
Negit IslandBlack point
Mono Lake former shore lines In 1963 the elevation of the lake was at 6392 ft.
This deck was built in order to set a goal of where Mono lakes water should rise too.
Mono Lake
Former Shore lines
Tufa
Tufa is formed where there was once a hot water spring under water, the bubbles that come through up to the surface.
Glaciated Valley and Moraines
Panum Crater Glaciated Valley
Convict LakeApril 9, 2001
Around 3:00pm
Convict Lake and Oldest rock formation
Lateral and Terminal Moraines
Owens RiverApril 9, 2011
Around 5:30 pm
Owens River & Swallows Nests
This river used to flow into Owens Lake but it has been transitioned to California and LA aqueduct.

Field Questions
1. Mormon Rocks Formation-A. This are is very important because this
is where the Andreas Fault is and where a lot of seismic activity and earthquakes start.
B. The rocks are formed when there is a earthquake the bottom of the stream bed is then inverted and starts to form the rocks upward the oldest rocks being at the top. The rocks are formed because the water from the stream picks up all the debris and rocks and then it dries with the intense heat and cold desert temperatures.
2. Cinder (red) Hill/Fossil FallsA. I saw the red cinder hill, red
cinder all over the ground, the Lava rock formations, the house rings, and Fossil falls which are very high up.
B. 3 things that show evidence of Native American habitation are the pyroglyphs, house rings and the broken obsidian.
Field Questions3. Mt. Whitney Interagency
CenterA. The Sierra Nevada Mountains
are shaped in a “U” form because they are made by glaciers and the Inyo/White Mountains are “V” shaped because water has been a main ingredient to their formation.
4. Analema- On April 9th the sub solar angle was at 60 degrees North.
5. Mono Lake-a. The land forms I saw at Mono
Lake were the Tufa’s, Islands, volcanoes.
b. 3 evidences of former lake levels:
• Tufa’s that are far away from the water away from the shore lines which had to grow in the actual water.
• You can see the water levels on the mountains surrounding the lake.
• The wooden panels of where the deck was connected to the water.
