My buddy and I were up there a week ago, also. I've pretty much ruled-out, for myself, either the Gibbon, or Firehole, falls. The clues looked pretty good from home, but once on the ground...not so good. We did find one place that looks decent, but didn't check it. I may go up there this week, and take a look. My buddy is running a huge goldmine construction project south of Winnemucca, so doesn't get home often, and I've spent enough time in the Park, that I'm not really comfortable wandering around in the woods there alone. So, I have to think about it, or wait until this fall.
