Historic Structure and Cultural Landscape Reports for Devils, Long, Michigan, Outer, and Sand Islands
Historic Structure reports and Cultural Landscape reports (HSR/CLR) have now been completed for Devils, Long, Michigan, Outer and Sand Islands within Apostle Islands National Lakeshore (a separate HSR/CLR for Raspberry Light has already been completed). These documents provide a comprehensive understanding of structures and landscapes associated with the light stations, as well as how they collectively tell the intriguing story of the history of navigation in the Apostle Islands region. These documents are being used to guide management and protection of these important cultural resources. An Environmental Assessment (EA) was also completed to analyze the environmental impacts of implementing various management actions needed to protect cultural and natural resources, improve visitor experience and access, improve public health and safety, and provide more effective management of the light stations within the park.
