The potholes in canyons like Imlay and Heaps are full of frogs at certain times of the year. Here is one thing that I have been curious about. How do they get started in such places and how to they survive getting blasted by flash floods? There are fish in the Left Fork North Creek above the last rappel. How do they get started in such places and also survive being blasted by flash floods? It seems that flash floods would flush the fish from such places. Any thoughts?
