Black Canyon, situated in the Pahrangat Valley National Wildlife Refuge, contains prehistoric petroglyphs that appear to be unique to this location. As such, they are, collectively, listed on the National Register of Historic Places. The canyon is 10 acres in size and there are approximately 100 glyphs that feature various rectangular and oval shapes; some have with heads and limbs and others do not. The glyphs were studied in 2009 with the help of a large group of volunteers. It is possible for visitors to see the glyphs. It is speculated that the canyon served as corridor through people could travel between the White River and the lower part of the valley, to reach the marshes there.
