An enjoyable video about the two geologic features responsible for a good chunk of the vulcanism in New Mexico, the Jemez Lineament and the Rio Grande Rift.
Prior to the 1978 Summer field season, spent on the Eagle Mts., we four "Eagle Mts. rangers" and our professor made a quick visit to the Jemez Mountains. Though I didn't get "enough" slides taken of the caldera crater, here are a few images of the Bandelier Tuff overlying older Rio Grande Rift-related basalts east of the caldera crater.
