Looking down Imperfect Impasse from approx 5,400 after ascending and exiting
Not always passable. The schrund that protects the summit was totally collapsed in August 1997. We couldn't find a way around it.

Another view of the collapsed schrund in August 1997. Bit of a bummer as it takes alot of energy to get to this location.
Just below the summit block of Mt. Challenger
