I can't speak for Potanipo but I was on Melendy last Thursday which is in the same area and actually sets up faster (smaller). After about 45 minutes of listening and feeling the ice crack, pop, and sizzle I bailed on it, there was about 4" but it was breaking down. It has gotten worse since as you would expect and when I drove by it this morning the bob house was off and it looked sketchy. I can't imaging Potanipo is any better, especially with the flow that goes through it.
