An interesting day riding yesterday, we had to wait out a flash flood in Eagle Canyon, which is in the San Rafael Swell, in Utah. Not a rain cloud in the sky, and suddenly we are facing a good strong stream of water coming down the canyon right in front of us. We barely had time to pull over to somewhat higher ground. It never became a really large flood, but ran steady for well over an hour before we were certain it was decreasing, and not continuing to increase.

That pool of water ahead looked harmless enough, and I was tempted to try it. We came back the next day after the water had dropped, and that small pool of water was a 3 foot deep hole. I would have swamped the UTV if I would have tried to drive through it.

We turned around and went with the flow, because it was a shorter distance to get to an exit from the canyon.

I've been exploring the west for a long time now, and haven't come across too many of these. It's a wonder we don't see them more often.
I have since been told that the rain storm that caused this flood, was over 50 miles north of where we were at. We never even saw the rain storm.
