Historically the island is part of the broader coastal environment of southeastern Alaska and has been incorporated into federal land management frameworks. Much of its land remains in a near-natural state with limited development.

Geographically it sits in southeastern Alaska at approximately 56.54°N, 134.05°W, within the Alexander Archipelago among many other narrow forested islands and channels. Nearest significant communities are small coastal towns in southeastern Alaska rather than large cities.
