The El Capitan Passage, a 27-mile long waterway dividing Prince of Wales and Kosciusko Islands, offers many ways to get closer to nature. Today we'll stretch our legs on an old logging trail on the way to El Capitan Cave, the longest mapped cave in North America. Here, fossils of ice-age bear, seal, fox, and caribou bones dating as far back as 10,000 years ago were discovered and we'll talk to Forest Service Rangers about karst and the geologic forces that created this intricate cave system. Then, as the sunset casts its shadows over the Karheen Passage and Tonowek Narrows, relax over a delicious meal and maybe indulge in a sauna or hot tub soak before bed.
