At the ridge crest, turn left for Angel's Rest. If you continue east, you're on the separate #415 extension toward Wahkeena Springs, not the usual viewpoint out-and-back. The short summit path reaches a long spine of platy andesite, part of a roughly million-year-old lava flow from Larch Mountain. The rock opens to a broad, roughly 270-degree view: the Columbia far below, Beacon Rock and Cape Horn across the river, and Portland and Sand Island toward the west. On the approach, a split-rail viewpoint frames Silver Star Mountain; check back for the keyhole profile of the point.
The final rock spine is exposed, with steep drops on three sides and no protective rail. The Forest Service warns of fatal falls here. Stay well back from the rim. From safer ground, keep the river and far cliffs in the frame so the photo shows the height of the bluff. Penstemon, iris and Oregon sunshine bloom on the open crest in late spring.
