Fwiw we couldn't get over Indian Creek either, The snow wasn't super deep just wet and cement likeWe did not. Got as far as the first crossing of Lee creek at 6,100'. After getting across the creek, Mark was still going pretty good - he had flotation going and no telling how much further he could have gone. I was just plowing down and going nowhere trying to follow him in it though. That was after winching to get up out of the creek.
Flotation keeps you going in that stuff, but it can stab you in the ass too, once you do break through and high center. Good spot to eat and let the kids play then call it a day .
