Gale Hills Formation is named for exposures in the Gale Hills, Clark Co, NV. Type section is located in T20S R65E [Callville Bay and Government Wash 7.5' quads]. Consists of three units (ascending): 1)basal conglomerate made of rounded pebbles and cobbles derived from several Paleozoic and Mesozoic formations, succeeded by layers of fine-grained sand, silt, and clay (similar to the Willow Tank Formation); 2) Sand derived from the Aztec Sandstone, abruptly grading into coarse bouldery deposits (resembles the Baseline Sandstone); 3) bouldery rubble derived from carbonate beds in [local] Paleozoic formations, grading into finer material, with local ash beds (resembles the Overton Fanglomerate). [Thickness is greater than 7500 ft, as shown on measured section.] Overlies the Aztec Sandstone; underlies the Horse Spring Formation. Age is Cretaceous(?) or Tertiary(?).
