Hole in the Wall Lake

Formed just off Oregon state route 86 by a landslide that dammed the Powder River in the fall of 1984. The slide was triggered by a combination of heavy rains and weak, incompetent rock (Jacobson et al., Oregon Geology, May 1985). At this time the highway had been rebuilt to bypass the new lake, and AFAIK the new alignment is still there.
