3. Near Coalinga, CA
Took dirt road to a dirt
lot, walked up a path
full of weeds and rocks,
led to big hills, walked
throughout the fields
4. In 1865-Interest in oil inspired an oil rush
The interest started die out because of shipping
problems
In 1890-second oil rush happened because coal mines
had little value
Coalinga was the third largest shipping point for
railroads in California-mostly all connected to oil
production
(“History of Coalinga, 2011”)
5. On May 2,1983 there was a
earthquake with a
magnitude of 6.4
This earthquake was
triggered by an 0.5-meter
uplift of Anticline Ridge
northeast of Coalinga
Triggered rock falls and
rockslides
Pumping units, storage
tanks and pipelines from oil
fields were destroyed
(“California Earthquake Map
Collection, 2005”)
6. I believe this rock is a
Mudstone-made of
hardened mud
The rock was found in a
creek, which was made
from water and mud,
known as a sedimentary
rock
I thought it was a
claystone, but the stone
was not fully made by The rock is grey, hard to
clay break, solid, hard to scratch and
(“MUDSTONE, 1995”) is surrounded by other pieces of
mudstones
7. This a type of
sedimentary rock because
it was found in a mud
area along a small creek
It’s a claystone- rock
made from clay, turns
hard, doesn’t get soft
when touched by water
(“Claystone, 2011”)
I thought it was a Rock is orange with white,
shows cracks, piece of outer
siltstone, but doesn’t layer is broken off, hard clay
show layers rock
8. Sandstone forms where
sand is laid down and
buried
(“Sandstone, 2011”)
The sandstone is known
to be a sedimentary rock
(“Sandstone, 2011”)
The sandstone is very
similar to the Quartzite
stone- which is a Found the stone in the dirt, the
metamorphic rock surface is covered in dirt,
(” Quartzite, 2011”) cracks all over the side, color
pink, stone has different
angles.
9. As you can see from the
image, life is hard to
find during this season
It is like a desert climate
Animals don’t come
out, plants are dead or
almost dead
You have to walk all
over the hills to find any
form of plant
10. The Yellow Coneflower is also
known as the Ratibida Pinnata
Grows best in full sun to
partial shade-medium to dry-
medium soil conditions
They have stiff and rough
feeling coarse leaves, yellow
flowers that have droopy soft
yellow rays
The cone-like green centers
eventually change dark brown
Insects like butterflies and
bees are attracted to this Some of these flowers are half
flower dead-exposed to too much
heat, and some are alive, the
(“Ratibida pinnata, 2011”) stems are a mixture of brown
and green
11. The Coneflower is called Echinacea
The Echinacea is self evolutionary, it blends into its
environments , several different kinds of Echinacea
Types of Echinacea
◦ After Midnight: Purple-Red, bloom July-August
◦ Bright Star: Purplish-Pink, bloom July-August
◦ Coconut Lime: White, bloom July-August
◦ Coral Reef: Orange, bloom mid-late summer
◦ Doubledecker: Pink, bloom during summer
◦ Fancy Frills: Pink, bloom during summer
◦ Fatal Attraction: Purplish-Pink, bloom during summer
◦ Firebird: Red-Orange, bloom Mid-Late summer
◦ Flame Thrower: Orange-Yellow, bloom Mid-Late summer
(“Echinacea, Coneflower, 2009”)
12. This tree is hardy and thrives
in warm, wet winters and dry
summers
It’s a diverse tree with more
than 700 species
Grow from 30 to 200 feet
They could produce white,
pink, red and yellow flowers
It’s leaves produce a waxy oil
that prevents water loss in hot
weather
It is used to reduce
inflammation and fever
Some of the leaves are dying,
(“Eucalyptus Tree, 2011”)
pieces of the tree are falling off
and there was a lot of bugs flying
around it.
13. The Eucalyptus tree could be found in regions of
South America, South Africa and India
(“Eucalyptus Tree, 2011”)
It is one of the oldest trees on earth that dates
back to about 50 million years
(“Eucalyptus Tree, 2011”)
Evolved from rainforest precursors because of
changes in landscape, soils and climate
(“About Eucalypts,2011”)
They are native to Australia
(“Eucalyptus Tree, 2011”)
The essential oil can be toxic in large amount
(“About Eucalypts,2011”)
14. Most have yellow, red or
purple flowers
All have flat, fleshy pads
that look like large leaves
Pads are modified
branches or stems
Stems serve as water
storage, flower
production and
photosynthesis
It is found in North
America The Cactus were small, had red
(“Prickly Pear Cactus, 1996”) flowers, were squeezed together
and had long spines
15. Represents about a dozen species of the Opuntia
(“Prickly Pear Cactus, 1996”)
There has been medical interest in this Cactus
Pectin contained in the pulp lowers levels of bad cholesterol
Fibrous pectin in fruit may lower diabetics’ need for insulin
Both fruits and pads of this cactus are rich in slowly absorbed
soluble fibers that help keep blood sugar stable
(“Prickly Pear Cactus, 1996”)
The cactus can be cooked into jams and preserved down
into a syrup as a base for jelly
(“Prickly Pear Cactus,1992”)
The sap from the pads can be used in first aid similar to the
Aloe Vera plant
(“Prickly Pear Cactus,1992”)
