In Thomas Bay, Alaska. Our Un-Cruise on American Safari dropped us off on shore in the small boats, and we went on what they called the "Arduous Mud Scramble". That it was. An awesome summer day, but this thing was still packed with mud. They literally hosed us down on the deck of the ship when we returned. Absolutely awesome hike with some pretty decent elevation. This followed the stream/waterfall pretty much the entire way. There were several volunteers rebuilding sections of the trail. Very well done :)
