i wonder if you just found the 1st hole then turned around and went back? myself and some family members stayed there a sat night about a week after the big storm and snow july/august and the pools were bigger than ever thanks to some ppl doing a lot of digging. took my wet beanie off inside the camper and in the morn it was frozen solid and another guy had serious frost on his dash haha. Interesting in the morning to see more steam rising from 3 or 4 spots on the other side of river and evidence of some rocks been moved, have to wait til the summer trip for further exploration was just to bloody cold
