A group of cinder cones of the Kolob volcanic field were constructed on the upper Kolob Plateau in SW Zion National Park. Spendlove Knoll (left) and Firepit Knoll (partially hidden by behind the white sandstone of Pine Valley Peak at the right) are seen here from Northgate Peaks. Lava flows from Firepit Knoll traveled left down Lee Valley to the south. These late-Pleistocene basaltic cinder cones form a dramatic contrast to the colorful rad and white sedimentary rocks of the Navajo Sandstone.
