Boundary Butte is a 4,934-foot (1,504 meter) elevation sandstone summit located south of Lake Powell, in San Juan County of southern Utah. It is situated on Navajo Nation land, 11.5 miles (18.5 km) northeast of the town of Page, and towers 1,200 feet above the lake as a landmark of the area. It lies on the Utah-Arizona border, hence its name.

Geology

Boundary Butte is a butte composed primarily of Entrada Sandstone, similar to Dominguez Butte 2.5 miles (4.0 km) to the north, and Tower Butte 2.6 miles (4.2 km) to the southwest. The Entrada Sandstone overlays Carmel Formation, and below that Page Sandstone at lake level. Above the Entrada layers is Romana Sandstone capped by Morrison Formation. It is located in the southern edge of the Great Basin Desert on the Colorado Plateau. Precipitation runoff from this feature drains into the Colorado River watershed.
