It's possible that other people have not done this loop faster, considering the number of strong athletes in Western Montana. Having done the route once, I'm confident that it can go faster. We took some time to enjoy the views and deviated from the ridge to refill from water and go for a swim on a hot late summer day. Knowing the route and which cliffs to avoid, would definitely help make a faster attempt possible. We wasted quite a bit of time navigating, downclimbing and climbing out of dead ends. Care is required on much of the ridge due to the copious amounts of loose rock.
