MULTIPLE PLEISTOCENE GLACIATION OF THE WHITE MOUNTAINS, APACHE COUNTY, ARIZONA
Field evidence indicates two episodes of glaciation in the White Mountains, separated by a considerable time gap represented by deep weathering of the older glacial material, stream entrenchment, and outpouring of basalt and cinders over the area. The snow-level depression at the time of the younger glaciation was 2700±640 feet below the estimated, modern snow level.
