About Petroglyph Island
Petroglyph Island has a trail leading to one of the only signs that indigenous Tlingit and Athabascan people lived in this area. From the west side of the island there is a trail leading to the center of the island where a flat rock exposes two circular petroglyphs. The importance of the confluence both spiritually and logistically could give numerous meanings to the symbols, none of which are known for sure.
The channels above Petroglyph island are constantly changing and determine the ease of access. Ideally, you want to find a channel to the west side of the island where boats can be tied up and the trailhead begins. Stopping at Melt Creek often means you cannot make it to Petroglyph Island. This is not always the case, but consider this as you chose campsites.
