The sparsely vegetated Santa Clara lava flow traveled 16 km to the south down Snow Canyon, cut through the colorful red and white rocks of the Navajo Sandstone formation. The flow, originating from two youthful cinder cones in Diamond Valley above Snow Canyon, was produced during one of the youngest eruptions in the Colorado Plateau/Basin and Range region. This Pliocene-to-Quaternary volcanic field north of St. George in SW Utah contains numerous basaltic cinder cones and lava flows.
