Crater Elegante
Crater Elegante is a 1.6 kilometer diameter depression outwardly
resembling a maar volcano, rising only about 50 meters above the
surrounding desert. It consists of flows and pyroclastics of alkali
basalt or hawaiite. Carbon-14 dating from deposits from a lake formed
after a collapse puts a minimum age for the small caldera at about 12,000
to 17,000 years. It reaches a depth of 244 meters. It is estimated that
the volume of material ejected during the culminating eruptions was at
least 162,200,000 cubic meters!
