USGS Topo · Published 2021About this map
Kupreanof Island dominates this coastal survey, where the dense woodlands of the Tongass National Forest meet the intricate shoreline of the Alexander Archipelago. The landscape is defined by the interaction of land and sea, featuring the sheltered waters of Douglas Bay and the isolated position of Moss Island just offshore. To the south, the seafloor is marked by McArthur Reef, an important navigational feature for those moving through the borough's coastal passages. This survey represents the area near the boundary of Petersburg Borough and Prince of Wales-Hyder Census Area, documenting the rugged coastal geometry of Mitchell Point and the vast protected lands managed by the TNF.
