6. 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.
7. Solar Power Plant
This picture shows the solar
power plant at the intersection of
the 395 Highway and the 58
Highway in California.
8. Doppler Radar Station
The Doppler Radar Station is
used for weather prediction from
Satellite Imagery.
9. Mine Tailings
These piles of debris are formed
from mining near Red Mountain
by the Rand Mining District.
12. SETI Towers
The SETI Towers are satellite
dishes that are searching for
messages from space. SETI
stands for Search for
ExtraTerrestrial Life.
13. 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)
14. Geese in Bishop
For a stop in Bishop, we parked
near a park with a stream that
had geese and Mallards in it.
19. Mormon Rocks Structure
The granular structure of the
Mormon Rocks sandstone shows
that it is comprised of
sedimentary rock over time.
20. 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.
27. 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.
28. 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.
30. 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.
33. Lone Pine Fault
The Lone Pine Fault is next to
Diaz Lake. The hills in the
background are the Alabama
Hills of California.
34. 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.
38. 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.
40. 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.
42. 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.
43. Volcanoes Near Mono Lake
The mountains around Mono
Lake are actually volcanoes that
have not recently erupted.
44. 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.
45. 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.
47. 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.
48. Old Mono Lake Size
Lines on the nearby hills, show
the shoreline of Mono Lake
hundreds of years ago.
49. Duck in Mono Lake
Wood ducks feed on brine
Shrimp in Mono Lake.
50. Whigens in Mono Lake
Whigens are another bird
species that feed on brine
Shrimp in Mono Lake.
51. Cormorant in Mono Lake
Cormorants are another bird
species that feed on brine
Shrimp in Mono Lake.
53. Panum Crater
Panum Crater is a Volcano that
has a smaller volcano inside of it.
This is the valley of Panum
Crater.
54. 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.
55. New Burn Area
A more recent wild fire shows the
charred remains of native plants
57. 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.
64. 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.
66. 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.
68. 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.
69. 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.
70. Field Question 1
Mormon 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.
71. Field Question 2
At 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.

72. Landforms Near Fossil Falls
The Volcano is green, the Lava
Flow is red and the Alluvial Fan is
blue.
73. Field Question 3
The 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.
74. Field Questions 4
Using 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 6th
, 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.
75. Field Question 5
At 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.
