Wind River Formation at Hell's Half Acre, Natrona County, Wyoming.

The Wind River Formation is a geologic formation in Wyoming in the Wind River Basin. It preserves fossils dating back to the Paleogene period. A recent study by Stanford suggests that fracking has contaminated the entire ground water resource in the basin.[1]
