Death Valley National Park - http://www.nps.gov/deva
Hottest, Driest, Lowest:
A superlative desert of streaming sand dunes, snow-capped mountains, multicolored rock layers, water-fluted canyons and three million acres of stone wilderness. Home to the Timbisha Shoshone and to plants and animals unique to the harshest of deserts. A place of legend and a place of trial.
