2018 Map of Bradfield Canal A-3 SE

About this map

Leduc River and Klahini River carve through this high-elevation glacial landscape within the southern reaches of the Tongass National Forest. The map illustrates a series of sharp ridges and deep river valleys typical of the Alaskan panhandle, where steep vertical gradients define the movement of water and ice. These drainage systems are central to the region’s topography, showing the complex interplay between fluvial action and the massive ice fields that have shaped the Ketchikan Gateway Borough. Surveyed in 2018, the map highlights the immense scale of the Tongass National Forest by documenting its interior peaks and glacial runoff patterns, providing a precise record of the hydrologic network that feeds into the broader Bradfield Canal system.
