Death Valley
Death Valley is one of
the driest and the lowest places in North America. This place once was all
under water, and there is significant evidence as the rocks was once sand
submerged. The oldest rocks in Death Valley were formed 1.7 billion years ago.
The lime and sand stone indicate that there was a warm shallow sea. Death
Valley lies between two plates cause an uplift, forming mountains. The next
phase of the Death Valley formation was the travelling volcano's. The move meant
the plates hot molten material welled up weakening the surface, and causing an
eruption. The volcanic activity moved towards the West, forming a chain of
volcanoes from Furnace Creek to Shoshone. Death Valley’s climate has been
changing for the past three million years, Death Valley was part of the last
ice age, and it was part of a large system of lakes. As the temperature started
to rise the lakes evaporated.
Death Valley was known for borax mines. The twenty mule train
was used to carry the borax that was mined out. It was closed later on, once Death
Valley became a National park only in 1994. The floor elevation is -85 m (-279
ft.) Area of 3,000 miles and is located
in Eastern California. Furnace creek located in Death Valley holds a world
record temperature of 56.7 degrees Celsius. During monsoon Death Valley has
flash floods. There are vast varieties of wild flowers during winter. There are
some fish (pup fish) that come with the water during monsoon most of them die
and end up being eaten by the coyotes.
I loved Death Valley and would like to visit again for to
understand a little more in depth its vast change in climate over a few million
years. From a sea to volcanic mountains, and to having steady droughts.
It really surprises me when we realize the kind of changes Death Valley has seen during the last millions of years and it continues to evolve...amazing hand of nature at work here.
