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
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”)
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”)
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
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
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.
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
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
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”)
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.
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”)
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
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”)
