Data Release for Geologic Map of the north half of the Lake Walcott 30' x 60' Quadrangle, Idaho

The northern half of the Lake Walcott 30 x 60 minute quadrangle shows the geology of the southern part of the Craters of the Moon lava field, the complex geologic features of the Holocene Kings Bowl and Wapi lava fields, and the southern part of the Great Rift volcanic rift zone. The long extent and distribution of skylights in lava-tube systems of the Horse Butte and Wapi Park lava fields are depicted on this map. 40Ar/39Ar and K/Ar age determinations give detail to the Holocene, late Pleistocene, and late middle Pleistocene volcanic for lava fields in this quadrangle. Most of the younger basalt eruptions (<150 ka) have occurred along the Great Rift volcanic rift zone, but two of the younger lava fields are located...
