The granite formation to the left of Half Dome is El Capitan. This vertical rock formation extends about 3,000 feet (900 meters) from base to summit along its tallest face.

The well tested in this project is located in the city of Brighton in Weld County, CO. Well SHABLE AB11-04P which is operated by Halliburton is one of the many wells in the Wattenberg field. Wattenberg field is a low permeability (“tight”) basin center gas field (Highley 12).Based from the Colorado Oil and Gas Conservation Commission in 1999, the Wattenberg field has approximately produced 1.75 TCFG, 76.4 MMBO, and 15.7 MMBW from all of the formation above. The primary source of hydrocarbon production in the Wattenberg field comes from the Muddy (“J”) Sandstone formation which currently has 1,900 producing wells. The Wattenberg formation also has a potential biogenic gas reserves for coalbed methane (CBM) production at the Laramie formation
The west coast of North America has been tectonically and volcanically active for billions of years. The Sierra Nevada Mountains in eastern California were born of volcanoes, and magma has been erupting in the Long Valley to the east of the mountains for over three million years (Bailey, et. al., 1989). However, the climactic eruption of the region occurred relatively recently in the region's geologic history. About 760,000 years ago, a huge explosion of magma warped the Eastern Sierra into the landscape that exists today. The eruption depleted a massive magma chamber below the earth's surface so that the ceiling of the chamber imploded, forming what is now known as
Stratum 3 in the Blue Mountain site lacks any evidence of settlement or subsistence; on the other hand, this could be evidence that the people who were there were nomadic rather than sedentary. The 4,534 debitage pieces and 234 cores suggest that it was a hunter-gatherer society and they used local obsidian which means that they could have had no contact with other people and likely did not travel very far. The majority of their tools were also made from the outer part of the cores.

The Upper Yosemite Falls hike is fast becoming one of the most popular hikes in Yosemite. Being the tallest waterfall in North America, climb this day hike and you will be rewarded with some amazing vistas of the Yosemite Valley from the top of the falls. The reward is worth the effort! Be forewarned, on 3-day summer weekends, expect lines of people hiking up to Upper Yosemite Falls like a trail of ants.
May 18, 1980 was a day that dawned sunny and beautiful. Mt. St. Helens stood out beautifully against the blue sky. The mountain had been rumbling quite a bit the past few days, and geologists were watching it carefully and monitoring vibrations. There had been a series of earthquakes from around March 12, up until present day. Over 170 earthquakes hit that were higher that 2.5 on the Richter scale in that short period of time. The earth shook with an earthquake that hit 5.0 on the Richter scale, at around 8:32 in the morning. That did it. Mount St. Helens blew apart with the force of over 500 times more powerful than the atomic bomb. The lateral blast traveled at over 300 miles an hour, and destroyed 230 square miles of forest in just 3 minutes.
Imagine a single event that can kill 57 people and 7000 deer and elk. Snap trees like a toothpick, and turn the sky grey for 15 days. Now, stop imagining, Mount St. Helens, in the Cascade Range of southwestern Washington State, erupted. On May 18th,1980. According to (Campbell 371), “At least $1 billion in economic damage was reported”. The eruption of Mount St. Helens took many lives, and devastated America. Mount St. Helens destroyed more than 230 square miles of ancient forest.
Yosemite was first protected in 1864 by Abe Lincoln,but it was actually a park in 1890 buy Robert Johnson and John Muir.You can find Yosemite in the granet heart of California (in the middle).But with in 12 acres wide!In the center of California.”What makes Yosemite a special place?” you might ask, well Native americans were the first people to live for a long time of the Valley.At Yosemite you can go hiking,backpacking, camp, tours with rangers,interpretive programs, and biking.Or you can visit waterfalls and glaciers.Can you believe this that a waterfall is as tall as 2 ½ thousand feet drop good luck taking a shower with that.Yosemite National Park became a National Park because of
It is currently the largest exposed granite in the world weighing approximately one trillion pounds; although, only one third of the mountain can be seen as a majority of the mountain expands below ground as far as North Carolina. The enormous pluton mountain, as scientifically identified by geologist, was formed by a complex folding and faulting that had subsequently created the Blue ridge mountains. Though what remains as a mystery to many geologist is as to how such a massive granite mountain has become exposed. Although there are several theories that have been publicated to explain such a phenomena none are substantial or advocated the most. While the origins of Stone Mountain are elusive, the correlations of this landmarks with american history are intricately
In far Northern California, about forty miles south of the Oregon-California border, resides the second highest mountain in the Cascade Range and the fifth highest mountain in California. The Cascades are part of the “Ring of Fire,” which is a ring of volcanoes and earthquake sites, around the borders of the Pacific Ocean. Mount Shasta can be seen for several hundred miles and has struck viewers with its remarkable beauty since it was first seen. Mount Shasta towers at 14,162 feet, remains snow-capped throughout the year and is often shrouded in oddly shaped lenticular clouds, or fierce storms that hide it from view. It is awe-inspiring in its geography and geology,
In June 1864 the Yosemite Land Grant was signed by Abraham Lincoln, which deeded 39,000 acres of the Mariposa Big Tree Grove and Yosemite Valley to the State of California (Hawken 40). It was an unprecedented piece of legislation, having almost universal support from private business, environmentalists and Congress. Sparked largely by the de-barking of “The Mother of the Forest”, one of the oldest sequoias in Yosemite’s Mariposa Grove, several years earlier (Hawken 39). The Yosemite Land Grant was the first piece of legislation founded on the principle that nature needed to be preserved and protected from humans (Hawken 40). After nearly a century of clearing many forests on the East Coast, affording protection to land on the West Coast was a novel concept.
This painting is for the falls of Yosemite which looks very amazing with the water of the falls coming down and the two men enjoying the view. The colors are very attractive; the artist did a good job matching the colors to create a real picture.

When I was in 7th grade, the whole entire grade suggested that we should go on a camping trip. We had many places to choose from, but we all agreed on going to Yosemite. The reason we chose Yosemite is because we wanted people to stay away from their video games and electronics for a couple of days and actually enjoy what beautiful things God had made and what the outside world has to offer. It was an amazing trip and we did have many unforgettable memories. But one memory I had was on the second day of the trip, it was the day we started to do activities with our group leader. We hiked up a waterfall, played some games, and also took lots of pictures. It was a very tiring day and when we were finally done for the day, It was
