Look at how the creek spreads over the rounded lip before it narrows into the pool; the basalt wall gives the falls its distinctive profile. A stereograph of Horsetail Falls made by photographer Joseph Buchtel, probably in the 1860s, is part of the Gorge’s early photographic record, and the descriptive name has lasted on maps.
For a phone photo, include some of the basalt face and the pool rather than filling the frame with white water alone. The cliff shows the waterfall’s shape, while the pool gives it context. Tables near the falls make a picnic an easy addition; otherwise, this is a useful short stop between Multnomah Falls and the Gorge’s other highway-side sights.
