The Lowest Point
In California’s Death Valley, Badwater Basin lies 282 feet below sea level. It is the lowest point in North America and sits only about 85 miles from the summit of Mount Whitney, the highest point in the contiguous United States.
This extraordinary contrast is created by the Basin and Range landscape, where the crust has been stretched into alternating mountain ranges and deep basins. In the desert, enclosed basins collect salts and sediments while nearby mountains rise sharply above them.
The Highest Point
The nation’s highest summit is Denali in Alaska, rising to 20,310 feet. Alaska contains some of the country’s most dramatic scenery: broad tundra plains, steep mountain ranges, volcanic islands, and Arctic coastlines.
In the lower 48 states, Mount Whitney reaches 14,505 feet in California’s Sierra Nevada. The range is high, rugged, and dense, with famous landscapes preserved in places such as Yosemite National Park.
A Land of Contrasts
The vertical extremes are not isolated curiosities. They reflect the broader structure of the West, where the Rocky Mountains, Intermontane Plateaus, Sierra Nevada, Cascades, and Pacific Coast Ranges create a complicated sequence of heights and depressions.
The Colorado Plateau adds another kind of elevation drama. Its high plateaus have been carved into cliffs, arches, mesas, and gorges, producing the landscapes seen at Grand Canyon, Arches, Mesa Verde, and Bryce Canyon.
The distance between Death Valley’s salt basin and Denali’s icy summit is a reminder that American geography is not merely broad—it is profoundly vertical.
