Boundary Peak, Mountain summit in Esmeralda County, Nevada, United States

Boundary Peak is a 4,007-meter mountain in Esmeralda County, Nevada, the state's highest natural point. Its summit is a jagged, triangular crest of pale tan and gray bare rock with sharp ridges and shadowed gullies, rising above dark green, densely packed vegetation on its flanks and a broad tan plain below. The peak lies in the Boundary Peak Wilderness of Inyo National Forest, less than half a mile from the California line.

The peak takes its name from its position less than half a mile from the California state line, the highest point in Nevada at 13,147 feet. It is the northernmost summit above 13,000 feet in the White Mountains, within the Boundary Peak Wilderness of Inyo National Forest. By prominence, 253 feet, it is a sub-peak of the taller Montgomery Peak across the line in California.

Boundary Peak is a goal for highpointers, climbers who summit the highest point of each U.S. state; for Nevada that means this 4,007-meter summit, even though its 77-meter prominence makes it a sub-peak of Montgomery Peak. The name comes from the state line less than a kilometre away, and the peak lies in the Boundary Peak Wilderness of Inyo National Forest.

Visitors should exercise caution on loose rock, especially during the steep final sections of the climb where footing becomes unpredictable. Starting early in the day provides adequate daylight for safe navigation and descent.

Boundary Peak rises only 253 feet (77 m) above the saddle linking it to Montgomery Peak, which stands 13,441 feet (4,097 m) across the California line less than a mile away. Because of this small prominence, most definitions treat Nevada's highest point as a sub-peak of its taller neighbour.
