About this map

Port Snettisham dominates the maritime geography of this coastal region, where deep water meets the steep, timbered slopes of the Tongass National Forest. The landscape is defined by its dramatic shoreline features, including Point Styleman and Point Anmer, which serve as critical navigation points along the inlet. The inland terrain is characterized by sharp elevation changes, particularly around the drainage of Mist Cr, which flows toward the protected waters near Mist Island. A significant administrative boundary bisects the waters here, marking the divide between the Juneau City and Borough and the Hoonah-Angoon Census Area. This layout reflects the area's role as a rugged maritime corridor, where human activity is largely dictated by the deep-water access of the sound and the steep, restricted topography of the national forest.
