Would anyone care to guess when a person is most likely to encounter clear water in Grand Canyon? I've been there in late August and early September, and the water was dense with silt.
Yes, of course. But we all know that the river sometimes runs clear. Any cloudburst in a sidestream will bring in a silt load, and August is monsoon season, so that is the highest likelihood for silted water. But when is the highest likelihood for clear water?
