The little cabin is actually a generating wheel, up above it and to the left is the Johnny Sack cabin, (Johnny was one of the trappers/mtn. men in the Island Park area.) It is a neat, albeit, short tour in the summer the wheel no longer generates electricity. Big Springs is the beginning of the Henerys Fork of the Snake River and unfortunatly for Samuri, you cannot fish until about 3 miles downstream. For lodging try Island Park Village, Ponds Lodge and Phillips Lodge. Island Park is one of my favorite areas, wish it was about an hour closer.
