2021 Map of Bradfield Canal A-4 SE

About this map

Burroughs Bay serves as the terminal basin for several significant glacial waterways in this remote section of the Tongass National Forest. The convergence of the Unuk River and the Eulachon River creates a complex delta system characterized by the Willow Islands, where the braided river channels meet tidal waters. To the east, the Klahini River feeds into the bay, while the land rises sharply toward the peak of Spur Mtn in the north. This 2021 study documents the contemporary coastline and hydrology of this uninhabited wilderness, illustrating how the glacial runoff patterns and silt deposits continuously reshape the estuary at the head of the canal. The absence of roads or developed settlements highlights the maritime-dependent nature of this region's geography.
