    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?

    It's probably not exactly the same thing, but in rivers that have occasional high-water events native species of fish do much better than invasive species of fish (likely because they have adapted to know what to do during those events after long periods of time). In a river that is dammed and the flow is controlled invasive species usually take over. I would guess the fish and the frogs in these canyons have been around for a long time and have adapted to being able to survive a flash flood. Also, its possible they got there in the first place by being swept into that location during a flash flood.

    Yes, almost surely correct.

    I don't know if they could be swept into the technical portion of the Subway from a flash flood.

    I can't figure out how they would get there. Maybe the falls at the last rappel either didn't exist or was much smaller when the fish migrated upsteam, but if so the fish must have been there, a very long time.
