Bandera Volcano Ice Cave, also known as Zuni Ice Cave, is a lava tube cave in New Mexico with an internal temperature significantly less than above-ground summertime ambient temperature; it contains perennial ice.[1] The inside temperatures can fluctuate between Шаблон:Convert. Some areas of the ice cave never reach above freezing. For years, local Indigenous people used the cave to store food.[1]
Geology
The lava tube was formed during the Bandera Crater eruption sometime between 9,500 and 10,900 years ago, during one of the many basaltic eruptions in the Zuni-Bandera volcanic field over the past million years.[2][3] The crater's cinder cone is 900-feet high reaching 8,309 feet above sea level.[4]
The eruption produced numerous formations in addition to lava tubes including a cinder cone, collapse pits, spatter cones and lava spine. The type of lava is ʻAʻā which is more viscous than pāhoehoe.[1] There are many lava tubes and several ice caves in the area including Giant Ice Cave.[4] One has been developed as a commercial ice cave near the Candelaria Trading Post.[3] Lava tubes in the area, "some dating back 115,000 years, formed a network of underground tubes stretching for 17 miles — the longest such system in the continental United States."[4]
Location
The cave system is located in the El Malpais lava field within the boundaries of El Malpais National Monument. The cave's location is N34° 59.556', W108° 04.926'.
