White River Narrows Archaeological District
Placed on the National Register of Historic Places in 1975, the White River Narrows Archaeological District northeast of Hiko features one of the largest concentrations of petroglyphs in the state. They are around 4,000 years old belong to the Pahranagat style of rock art. The district (the coordinates are approximate) is located within the Weepah Springs Wilderness, which is part of the Basin and Range National Monument. The glyphs were discovered by settlers traveling westward in the 1820s.
