Death Valley Earth at 134 °F (56.7 °C) on July 10, 1913, as well as the highest recorded natural ground surface temperature on Earth at 201 °F (93.9 °C) on July 15, 1972. Located near the border of California and Nevada, in the Great Basin, east of the Sierra Nevada mountains, Death Valley constitutes much of Death Valley National Park and is the principal feature of the Mojave and Colorado Deserts Biosphere Reserve. It is located mostly in Inyo County, California. It runs from north to south between the Amargosa Range on the east and the Panamint Range on the west; the

Furnace Creek and the Amargosa River flow through the valley but eventually disappear into the sands of the valley floor. Death Valley also contains salt pans. According to current geological consensus, at various times during the middle of the Pleistocene era, which ended roughly 10,000–12,000 years ago, an inland lake referred to as Lake Manly formed in Death Valley. Lake Manly was nearly long and deep, the end-basin in a chain of lakes that began with Mono Lake in the north and continued through multiple
