Bullfrog Marina, Lake Powell, Utah

While we were in the information centre, we overhead the ranger telling someone that there were flash floods fairly close by.  (The way it was phrased was "the river is flashing".)  We were going in the opposite direction, but later that day it poured down, which made the gravel road on which we were driving  turn to mud.  I was glad when we got to our motel that day.

Those are mostly houseboats, which are taken out on the lake.
