Rain God Mesa is a 5,921-foot summit on Navajo Nation land in the Monument Valley area of northeastern Arizona, rising steeply above the desert in a broad table-like form. Its name comes from Navajo religious tradition, recalling prayers and thanks to the Rain God for water, and water streaks on its south side visibly connect the landform to that meaning. The mesa drains into Gypsum Creek, a tributary of the San Juan River, and is composed of rock layers ranging from Permian to Late Triassic age. Those contrasting layers helped shape the isolated buttes and mesas that define Monument Valley.
