New Mexico Lava TubeTAMPA, FLORIDA—Based on a press release launched by the College of South Florida, a world group of researchers led by geoscientist Bogdan Onac means that Ancestral Puebloans survived 5 intervals of drought in western New Mexico by melting ice preserved in a collapse what’s now the El Malpais Nationwide Monument. Throughout years with regular temperatures ice soften would depart shallow swimming pools of water close to cave entrances. However throughout hotter and drier intervals, when the shallow swimming pools of water failed to look, the scientists suppose Ancestral Puebloans traveled into one explicit cave to gather ice from an historic ice block. They discovered deposits of ash, charcoal, and pottery within the cave, and charcoal and soot within the surviving ice core. Radiocarbon courting of the charcoal signifies that the small fires have been constructed between A.D. 150 and 950.
