Hells Gate sits on river bottom exposed after the great ice age floods about 15,000 years ago. At the south end of the park are basaltic columns from the Pomona flows 14 million years ago. Hells Gate State Park was also the site of a Nez Perce village. Little is left of the village now, but depressions south of the campground are the remnants of pit houses used for years by the Nez Perce as they fished for lamprey near Asotin Creek.
