This place is so odd. The attraction is a dry water fall (not a lake bed) that formed when the last ice age was ending and a river formed from melting ice but the river was jostled by volcanic and earthquake activity when caused the river to become a water fall. It has since dried up like most of this part of the country and most of the remaining ice age water is trapped below, coming up as ‘fossil water’ in springs. The fossil falls rocks are basalt mostly but have been pummeled by water and have smoothed and eroded. There’s also said to be obsidian flakes on the area.

Anyway, this campground is simple/primitive but has excellent cell service, low prices, and an interesting attraction.
