Millions of years prior to the actual sinking and widening of Death Valley and the existence of Lake Manly (see Geology of the Death Valley area), another lake covered a large portion of Death Valley including the area around Zabriskie Point. This ancient lake began forming approximately nine million years ago. During several million years of the lake's existence, sediments were collecting at the bottom in the form of saline muds, gravels from nearby mountains, and ashfalls from the then-active Black Mountain volcanic field. These sediments combined to form what we today call the Furnace Creek Formation. The climate along Furnace Creek Lake was dry, but not nearly as dry as in the present. Camels, mastodons, horses, carnivores, and birds left tracks in the lakeshore muds, along with fossilized grass and reeds. Borates, which made up a large portion of Death Valley's historical past were concentrated in the lakebeds from hot spring waters and alteration of rhyolite in the nearby volcanic field. Weathering and alteration by thermal waters are also responsible for the variety of colors represented there.
Zabriskie Point is a part of the Amargosa Range located east of Death Valley in Death Valley National Park in California, United States , noted for its erosional landscape. It is composed of sediments from Furnace Creek Lake, which dried up 5 million years ago—long before Death Valley came into existence.
