A survey of backcountry and wilderness campsites at Isle Royale National Park reveals that the park?s policies for managing visitor impacts have been remarkably effective in limiting the areal extent of camping-related disturbance. However, the dense spatial arrangement of designated campsites within backcountry campgrounds has also contributed to problems with visitor crowding and conflict. Only 9% of the sites had no other sites visible, while 22% had three or more other sites visible. Mean intersite distance was only 76 feet, and 34% of the sites are within 50 feet of another site. Visitor education programs and selected relocation of sites could reduce these social problems.
