We've been to this viewpoint before, on our Wallowa Lake/La Pine vacation. I thought I had pictures on the blog, but it seems not the case. Anyway, this is the same Crooked River that flows by Smith Rock, but here crooked river is at the bottom of a very deep crevasse.
I'll zoom out a bit, so you can see the distance.
Or you can look at Matt to get an idea, who doesn't like railings that don't reach his midsection.
