This site is located northeast of Isle au Haut near Boxam Cove on Marshall Island. This barren granite ledge is quite exposed to the southeast where there is little buffer from the open ocean.

Ornithological Summary

This ledge is not used by nesting birds, but instead is an important wintering area for Harlequin Ducks and Purple Sandpipers. Approximately 10,000 Common Eiders were observed in surrounding waters while molting during September 2005.

Conservation Issues

Oil spills and other overboard discharge pose the greatest threat to this site and surrounding waters. Its remote location and barren condition help to shield it from disturbance by recreationists.


The site is owned by the Maine Dept. of Inland Fisheries and Wildlife and managed as part of the Coast of Maine Wildlife Management Area. Spirit Ledge is closed to public use from April 15 to July 31, annually.
