05 Percent Shale:
Simplified maps of percent shale of the Navajo Sandstone over the entire study area were presented by Stanley and others (1971) and Kocurek and Dott (1983). Freethey and Cordy (1991) displayed a general lithofacies map of the Navajo Sandstone in eastern Utah, from which shale percentages were derived.
