Setting Hen is a prominent butte in Monument Valley on Navajo Nation land in southeastern Utah, visible from Highway 163 and named for its resemblance to a sitting hen from the southeast. Though often shown as a mountain, it rises steeply about 600 feet above the surrounding terrain within a quarter mile, helping define the valley’s distinctive skyline. Its slopes drain into the San Juan River basin, and its form reflects Monument Valley’s geologic history: softer Organ Rock Shale below and harder De Chelly Sandstone above, both from the Permian period, were shaped by differential erosion into the isolated buttes and mesas characteristic of the landscape.
