Firepit Knoll cinder cone is the largest of a cluster of cones at the northern end of the Kolob volcanic field on the upper Kolob Plateau. The northern cinder cones, of Pleistocene age, produced lava flows that traveled 10-15 km to the south. The cones were erupted through rocks of the Navajo Sandstone, forming the red-colored pinnacle to the right.
