Visual Characteristics

The primary feature is Palouse Falls, a 200-foot (61-meter) plunge waterfall. The falls are characterized by basalt rock formations, carved by glacial meltwater and the Palouse River. The canyon walls exhibit layered sedimentary rock. Vegetation is sparse, consisting of grasses, shrubs, and some coniferous trees along the canyon rim.
