I might not have written well enough, but definitely not walkable (almost certain death if you slipped- super fast water leading to a series of waterfalls), we did contemplate scooting across it, but the water came up too high- the water was running swiftly enough that if it hit your dangling leg, it would instantly flip you off into the water. Hope that makes sense.
We’ve had to use logs (walking on top, scooting and hanging onto) a lot traversing the Bob Marshall in the spring at high water, without them you might easily find yourself where it’s impossible to cross.
