Two cinder cones in the Diamond Valley of SW Utah were the sources of the voluminous Santa Clara lava flow, one of the youngest in Utah. The symmetrical southern cone, capped by a pristine crater, is seen here from the flanks of the northern cone. Lava flows from the two cones filled the lower Diamond Valley in the foreground and then spilled through a narrow gap to the right of the southern cone into Snow Canyon.
