This impact crater, 6 m wide and 1.5 m deep was produced by ejection of a 1.5 cu m ballistic block that traveled 5 km from the summit crater of Láscar (out of view to the right). An explosive eruption on February 20, 1990 destroyed 10-30% of the summit crater lava dome that had been emplaced in 1989 and produced an 18-km-high ash cloud. Aguas Calientes volcano rises on the horizon.
