About this map

Tongass National Forest surrounds the deep glacial carved waters of Endicott Arm in this early 1960s topographic survey. The landscape is defined by the stark transition from marine inlets to high ice fields, where Brown Glacier and multiple crevasses dominate the eastern heights. The drainage patterns of Sylvia Creek and Spruce Creek reveal the steep, intricate drainage basins typical of this coastal wilderness.

Evidence of historical activity is found south of the arm, including a Placer Mine located near Placer Lakes. This area, which also shows a lonely Cabin and the winding course of the Chuck River, provides a detailed look at the resource extraction and remote settlement patterns of the mid-twentieth century. The narrow reach of Fords Terror extends northward, terminating at a significant Tidal Flat that illustrates the extreme tidal dynamics of the region before modern navigational changes.
