The rugged Sierra Nevada mountain range rises beyond the reddish rim of the southern cone of the twin Red Cones. The southern cone is breached to the NW and fed a lava flow that joined with one erupted from the SW breach of the northern cone to form a flow 2 km long and 2 km wide that traveled west to Crater Creek. Devils Postpile National Monument, with its spectacular columnar-jointed basaltic lava flow, lies along the Middle Fork of the San Joaquin River, below the rugged Minarets and Banner Peak on the horizon.
