Volcán Tecolote is one of the youngest scoria cones of the Pinacate volcanic field and is located NE of Cráter Elegante. This complex cone contains faults and small craters, opens towards the NW, and was constructed on top of the Mayo cone. Large volcanic bombs, some with cores of older volcanic and non-volcanic rocks, are scattered across the southern and east crater rims and southern flanks. Six basaltic ‘a’a lava flows extend from the base of the cone.
