Sinker Butte

Elevation: 3,421 ft

Sinker Butte is located south of the Snake River by Idaho Power’s Swan Falls Dam. The dam is reached by a paved road from Kuna, Idaho.

Dan Krueger supplied the following information and photos:

I parked at Swan Falls Dam. Rather than the long road hike described by the trip reports you linked, I decided to take a direct route (picture attached). I spotted a break in the cliffs and decided I would explore it. It’s quite steep and easy class 3, but there’s no real exposure, so it was pretty easy even with a dusting of snow. Even though it wasn’t too bad I didn’t want to downclimb it so I followed the road on the way down (does anyone like downclimbing?, lol).
