Geology of Death Valley
Transcript of Geology of Death Valley
Is at one of the hottest/driest points in North America.
Has the lowest elevation in North America.
My dad went to Death Valley and said during the day it is so unbelievably hot. Yet at night time it gets very cold. BY ALENA RAGAN Discovery Death Valley was the 36th National park created.
Death valley was discovered because of the gold rush. A group consisting of young men (the Jayhawkers) and also consisting of two families split up on their way to California. The Jayhawkers had gone north while the families along with some single men traveled south. The Jayhawkers made it to California and were able to get some gold. Yet when they returned for their companions, all the single men had either gone wandering or had died and only the families remained. This is how Death Valley was named. Introduction
It became a national monument by President Hoover on February 11th, 1933.
61 years later, under President Clinton it became a National Park on October 31st, 1994 because it gained 1,200,000 acres. Area
The area of the park is close to 3,000 square miles.
It's area makes it larger than Yellowstone National Park. DEATH VALLEY NATIONAL PARK Rocks The rocks present in Death Valley are:
Metamorphic Rocks Lithology The oldest rock present that shows at the surface is called the Crystal Spring formation.
It was from the Precambrian times.
Thickness is near 2,000 ft.
Consists of Basal Conglomerate, Quartzite, Shale, thin and thick bedded Dolomite, Diabase, and Chert. Talc deposits when Diabase intrudes Dolomite only. Lithology Lithology Funeral Fanglomerate With the clay from the Furnace Creek Formation. It is composed of mainly Fanglomerate and other arid-basin deposits, but it contains some basalt flow. Thickness is 3,000 ft. The Titus Canyon Formation as a whole is
large, this is a section of it where the wall is made up primarily of Breccia. At the canyon it has exotic plantlife and wildlife which makes it a popular tourist attraction. The Butte Valley formation of Johnson. Buttes are formed by erosion when hard caprock covers a layer of weak rock, and is eventually worn away. This one is made primarily of Limestone. Lithology Formations at the East foot of Tucki Mountain. The formation here is made of thin-bedded Limestone and Dolomite overturned beds. Lithology The Lost Burro Formation is made up of Dolomite on the lower part and Limestone on the upper part. Quartzite rocks outline the formation. The Bonanza King Formation is made up of chemically precipitated Dolomite which formed in a marine setting. The white colored part in the rock is fecal matter from worms. The dark part is carbonate. Lithology The Carrara formation
The top part of this image is the Bonanza King formation.
The bottom is the Carrara formation. It is 1,000 feet thick on average. It is hard to tell what the exact height is because the Carrara formation sometimes loses layers because of shearing. Zabriskie Quartzite
The image shows 2 Zabriskie Quartzite hills. The hills are made by piles of massive and granulated Quartzite. It's thickness is over 150 feet. Lithology The Noonday Dolomite is 800 million years old.
A weird fact about it is that it is erosion resistant.
This image is of the Noonday Dolomite wall. The Kingston Peak Formation is made up of a mixture of different sediments and rocks. This formation's mix of such different rocks shows proof of glaciation around 700 million years ago. Tourist Attractions One reason why Death Valley is famous is because of one the highest peaks which is 11,000 ft. high is called Telescope Peak because the man who climbed it first felt as though he was looking through a telescope because it had such a detailed view. Tourist Attractions Probably the most popular tourist attraction is the Artist's Palette. It was made because of the many mineral deposits which caused colors to flood the hills. Is part of the Artists Drive formation. Tourist Attractions These sand dunes are famous because they are without flaw. You see then in an area known as Zabriskie Point. Another popular tourist attraction is Dante's View which is famous because from that point you can see 360 degrees for 100 miles! Mystery of Death Valley There is a mystery around the Racetrack Playa. It is a dry lake bed where boulders lay. Somehow, thought no one knows why or how (Scientists have no explanation). The 700 pound boulders move. We know this not because anyone has seen this happen, but because the boulders always leave a path behind them. Fun Facts!!!! The tribe currently living in Death Valley is the Timbisha tribe, they have lived there for close to 1,000 years. Animals we would recognize that live there are: bobcats, bighorn sheep, and mountain lions. In 1988 my dad visited Death Valley. He was one of the 692,267 visitors that year.
In 2011 however, the national park recieved many more visits with 946,867 visitors. Thanks for watching!!! Mr. Ragan at Zabriskie point (shown earlier)
