About Cottonwood Falls

Cottonwood Falls is a named ledge on the Spring River in Fulton County, Arkansas, about 5 miles south of Mammoth Spring and roughly a quarter mile upstream of Saddler Falls. It lies on the Class I-II Mammoth Spring to Hardy float, where most drops are 1 to 3 foot ledges, and is seen from a canoe or kayak; we found no public hiking trail or bank access to it.

Winter safety. Frozen falls are the one waterfall trip with a documented injury pattern: falling ice, and ice-glazed rock and trail. Wear microspikes, keep well back from the base and from overhangs, and never walk out on ice over moving water.

Estimate from Open-Meteo daily temperatures at the falls, the LiDAR-measured facing direction, and the nearest stream gauge. It is a likelihood, not a report from the trail.

The Terrain, Seen by LiDAR

Aircraft-mounted lasers measured this ground to within inches. Trees and buildings are digitally stripped away, leaving the bare shape of the land the water has carved.

The ground through the falls loses about 57 feet in steep steps rather than one leap. The ground at the falls is roughly 416 feet above sea level.

Most of the action is upstream: the ground drops about 64 feet in the 500 feet above the pin and flattens beneath the falls. Facing south, the falls sit in full sun for most of the day, best photographed early or late.
