Sunburn Risk at the Lowest Point in the U.S.: Death Valley

Death Valley, California—the lowest point in North America at 282 ft (86 m) below sea level (Badwater Basin)—is also one of the highest UV-exposure locations in the country.

• Low elevation → less atmosphere to filter UV radiation.
• Clear skies >300 days/year.
• High albedo from salt flats reflects UV.
• Extreme heat (record 134°F / 56.7°C) increases skin vulnerability.

Visitors can sunburn in 15–20 minutes at midday even in winter. Broad-spectrum SPF 50+, wide-brim hat, UV-protective clothing, and shade are essential.
