CINDER HILL/ FOSSIL
FALLS/MORMON ROCKS
3/10/12
3. MORMON ROCKS
Bunna Roeum The Mormon Rocks are a series of
cemented sandstone beds much more
resistant to erosion than the
surrounding gravel and silt sands. The
Mormon rocks lies right over the fault
that divides the Pacific and North
American plate and formed the rocks.In
1851, a group of Mormon settlers led
by Amasa M. Lyman and Charles C
Rich traveled through the Cajon Pass in
covered wagon on their way from Salt
Lake City to Southern California. A
prominent rock formation in the pass,
where the Mormon trail and the railway
merge.
4. GRANULAR STRUCTURE
Bunna Roeum
The Granular Structure The
Mormon Rocks are made up
of underlying sedimentary
rocks that have been pushed
through the eroded soil from
the San Gabriel Mountains.
5. SAN ANDREAS RIFT ZONE AND STREAM BED
The San Andreas Rift zone is a
Bunna Roeum
continental transform fault that
runs a length of roughly 810 miles
(1,300 km) through California in
the United States. The fault's
motion is right lateral strike slip
(horizontal motion). It forms the
tectonic boundary between the
Pacific plate and the North
American plate. The San Andreas
rift zone It is located along the dirt
/walkway you see in the picture to
the left.
6. CINDER HILL
Bunna Roeum
Red Hill,or Cinder Hill is a basaltic
cinder cone type of Volcano located
in the Coso Volcanic field near
Fossil Falls State Park
7. LAVA FLOW
Lava flows are streams of
molten rock that pour or ooze
from an erupting vent. Lava is
erupted during either
nonexplosive activity or
explosive lava fountains. Lava
flows destroy everything in their
path, but most move slowly
enough that people can move
out of the way.
9. FOSSIL FALLS
Bunna Roeum • During the last ice age the glaciers
had fomred in the Sierra Nevade. The
meltwater from the glaciers pooled into
lakes including Ownes Lake and the
Owens River. The river had traveled
through to Indian Wells Valley. Fossil
falls were formed when the river was
forced to divert its course over a basalt
flow, polishing and reshaping the rock
into a varitety of uniques shapes and
forms. All of the lava flows at fossil
falls are basaltc.
10. METATE HOLES
• Metate holes were created when pieces of debris would drill into the
basalt from the former water flow and would spin and create the
metate holes
11. OBSIDIAN FLAKES
• Flakes of obsidian can be found
Bunna Roeum in the area, for the Native
Americans would camp near
Fossil Falls and chip obsidian
from the Coso Mountains to
form their tools. Remains of rock
foundations from their homes
and obsidian chips from too
lmaking are evidence of various
occupations of this site between
12,000 and 3,000 years ago.
Obsidian flakes are a result from
the Volcanic glass.
12. PETROGLYPH
• The Indians who lived in this fossil
falls site were the ones who had
carved these animals/petroglyphs
pictured on the rock.
• Petroglyphs are also known as
rock engravings. Petroglyphs are
found worldwide and are often
associated with prehistoric people.
• Petroglyphs are rock carvings left
by the indians who came before us
and had told stories by engraving
them onto the rocks.
13. HOUSE RINGS
• House rings were former
homes for the Native
Americans. The native
Americans would stay here
during the summer for cooler
climates and during the winter
would migrate to the flatter
lands during the winter.
14. TRIP TWO
NORTHERN OWENS VALLEY
EASTERN SIERRA/LONE PINE/MANZANAR/ DIAZ
LAKE/ MONO LAKE/CONVICT LAKE
4/13/2012
15. DIAZ LAKE
Bunna Roeum Diaz Lake was created
Diaz Lake
from and Earthquake
along the Lone Pine
Fault in 1872. This kind
of lake is known as a
Sag Pond. The
earthquake caused the
land to sink and the
sunk water filled up the
pond creating Diaz lake.
16. Bunna Roeum
Lone pine fault
• In 1872 the large earthquake was caused by a vertical and right lateral
displacement along the lone pine fault. The earthquake caused the fault to move
back and created diaz lake.
18. ISLANDS AT MONO LAKE
Bunna Roeum
Paoha Island
Negit island
Paoha Island located on the left of this slide is a volcanic island that was formed in the 17th
century. The Negit Island is considered a volcanic cone. Negit island is dark because it was
composed by lava flows.
19. TUFA FORMATIONS
Bunna Roeum
tufa
When calcium rich springs flow up through the lake bottom the calcium bonds to
carbonates in the lake water. Together they form calcium carbonate, a type of limestone.
This solid material builds on itself forming a tufa tower. When the Lake level drops the
exposed tufa stops growing.
