Church Rock - Kayenta, AZ - Places of Geologic Significance on Waymarking.com

Like the better known Ship Rock, Church Rock is one of about 80 plugs on the Navajo volcanic fields. The eruptions appear to have been particularly violent. The pressure of dissolved minerals coming into contact with ground water produce an explosion moving through the layers of rock above the volcanic core. Church rock is composed of a rare igneous rock, minette which is a type of basalt. The surrounding, softer material has eroded away leaving the harder basalt plug. Church Rock is situated in Church Wash which is a very broad and level wash winding toward the San Juan river to the northeast. The wash is surrounded by sandstone cliffs typical of the area. Church Rock rises 500 feet from the wash to an altitude of 5862 feet. Travel on the Navajo Nation is restricted and requires a permit. The rock can be viewed from a turnout on U.S. Highway 160 at the given coordinates.
