Reddish scoria caps the circular rim of the southernmost of two cinder cones in the lower Diamond Valley of SW Utah. The northern cone in the middle distance is surrounded by a basaltic lava field. Light-colored rocks of the Navajo Sandstone at the left lie across a narrow gap from the southern cone; lava flows from the two cones spilled through this gap into Snow Canyon. The Pine Mountains rising in the distance are in part covered by older lava flows in the St. George basin.
