Which National Park Service national park contains North America’s lowest point?

Death Valley National Park contains North America’s lowest point, Badwater Basin.

Badwater Basin lies about 282 feet below sea level in California’s Death Valley. The basin is a broad salt flat formed in an enclosed desert valley, where water has no outlet to the ocean and evaporation leaves salts behind.

Death Valley National Park spans parts of California and Nevada. It was established as a national monument in 1933 and became a national park in 1994. At more than 3.4 million acres, it is the largest national park in the contiguous United States.

The park’s extreme elevation range is especially striking: Badwater Basin is near the valley floor, while mountains around the park rise thousands of feet higher. Death Valley is also known for exceptional heat, very low rainfall, sand dunes, colorful badlands, and the rare Death Valley pupfish.
