Church Rock 2

Near Kayenta Arizona on Navajo land is a series of volcanic diatremes. About 30 million years ago, magma pushed its way upward through cracks in the earth's crust. When the inland sea that covered the land drained - an extended, cataclysmic flow scoured away hundreds of feet of sandstone surface. These hard rock spires remain.. The distant structure in the background, right is called Agathla Peak.
