[2] Castle Rock is situated four miles (6.4 km) north-northeast of the Monument Valley Tribal Park Visitor Center, on Navajo Nation land.

Precipitation runoff from this landform's slopes drains into the San Juan River drainage basin.

[3] Topographic relief is significant as the summit rises 800 feet (244 meters) above the surrounding terrain in 0.25 mile (0.4 km).

The buttes and mesas of Monument Valley are the result of the Organ Rock Shale being more easily eroded than the overlaying sandstone.

This desert climate receives less than 10 inches (250 millimeters) of annual rainfall, and snowfall is generally light during the winter.
