Death Valley: The Hottest, Driest, Lowest U.S. National Park

Death Valley National Park (California/Nevada) holds the undisputed triple crown of extremes in the U.S. National Park System.

The Records

• Hottest Air Temperature on Earth: 56.7°C (134°F) at Furnace Creek, July 10, 1913 (WMO certified).
• Highest Ground Temperature: 93.9°C (201°F) at Furnace Creek, July 15, 1972.
• Driest: Avg annual rainfall 51 mm (2 in). Some years: 0 mm.
• Lowest Point in North America: Badwater Basin, –86 m (–282 ft) below sea level.

Why So Extreme?

• Rain Shadow: Four mountain ranges (Sierra Nevada, Panamint, Amargosa, Owlshead) block Pacific moisture.
• Basin Geometry: Deep, narrow graben traps heat; radiates from dark rock walls.
• Clear Skies: >90% sunshine; minimal cloud insulation → rapid night cooling but extreme day heating.

Beyond the Records

Surprising diversity: 1,000+ plant species (spring superblooms), 400+ animal species (pupfish in Salt Creek, bighorn sheep, kit fox), salt flats (Devil's Golf Course), sand dunes (Mesquite Flat), colorful badlands (Artist's Palette), Scotty's Castle (currently closed), Ubehebe Crater (volcanic).

Nov–Apr ideal. Summer: AC vehicles only, 4L water/person/day, no hiking after 10 AM. Cell service limited. It's not a park to "conquer"—it's a landscape to respect.
