1. What is allowed? Dredges, Highbankers, Hand tools only?
2. How deep is the water. Is it wade-able? In google earth the water appears to be deep and fast.
3. You mention bring a rope to lower yourself down. It appears there a a couple of trails in that area leading off the road. Are those available?
4. I assume snake boots are a good idea and how much of a problem is there with bears and lions as you had mentioned in your post about the Pinion Bridge site?
