Summary of Locations and Known Ages of Volcanoes in the Albuquerque Basin, Rio Grande rift
This is a prominent dark conical hill in the southern Albuquerque Basin. Its isolation, and dark conical form give the impression that it is a small basaltic scoria cone. But, in fact, it is a dark remnant hill of a fairly old (24 Ma) more andesitic lava flow.
