The youngest volcanic eruptions in Utah took place from the Ice Springs volcanic center. Root fragments from soil beneath the lava flow are C-14 dated at 660 ± 170 years old. Lava flows from the Ice Springs crater complex traveled about 4 km to the west and north, overlapping late-Pleistocene flows from the Pavant volcano. This view looks to the west from the rim of Crescent Crater, the largest of the overlapping cinder and spatter cones that fed the flows. Pocket Crater is the symmetrical cone in the center of the photo.
