# Dominguez Butte

Dominguez Butte is a 4,476-foot (1,364 meter) elevation sandstone summit located south of Lake Powell, in San Juan County of southern Utah. It is situated on Navajo Nation land, 13 miles (21 km) northeast of the town of Page, and towers over 700 feet above the surrounding terrain as a landmark of the area. Dominguez Butte has a brief appearance in the 1968 film Planet of the Apes, when a spaceship crash lands in Lake Powell.

## Geology

Dominguez Butte is a butte composed primarily of Entrada Sandstone, similar to Padres Butte 1.5 miles (2.4 km) to the north, and Boundary Butte 2 miles (3.2 km) to the south. 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.

## History

Francisco Atanasio Domínguez (1740–1805) was a Franciscan missionary and explorer who led the 1776 Domínguez–Escalante expedition. Guided by local Native Americans, the expedition attempted to cross the Colorado River at Lee's Ferry, but found it too difficult. A second ford of the Colorado River, named the Crossing of the Fathers, was successfully made two miles north of Dominguez Butte on November 7, 1776. The descent to the crossing was so treacherous that they had to carve steps into the stone to ensure the livestock could make it down to the river. Today, this ford lies beneath Lake Powell.
This butte's name was officially adopted in 1976 by the U.S. Board on Geographic Names to commemorate Atanacio Domínguez.
