It isn't at all unusual for the Nantahala in NC to be foggy. The water
comes
from the bottom of Nantahala Lake and is pretty cool year round. On really
hot days a thick fog can form right over the water. The first time I ever
ran it, visibility was about ten feet, as thick as I've ever seen it. I
was
a definite newbie to whitewater; I can still remember how hard my heart
was
beating and how dry my mouth was approaching the roar that was Quarry
Rapid.
I didn't see it until I was there, let the wave turn me sideways, and I
took
a swim.
I've paddled the Nanty so many times now I've lost count. I always look
forward to Quarry now, but it was absolutely terrifying that first time in
the fog.
Some examples of Nanty fog:

A typical summer Grand Canyon run has air temps in the 110s, and wateroften
below 40. That's a 150 degree total, but the yakkers all dress for
immersion. Even in a raft, you might be sweltering so badly that your head
is reeling, but you still can't bring yourself to hop in, even for a second.
