This is a remarkably early and detailed chart that is possibly the first complete survey of the territory's coastline since the transfer of sovereignty from Russia in 1867. Many features of the interior were taken from naturalist and scientific explorer William Healey Dall's 1865-68 Western Union Telegraph Expedition. Soundings fill the waters, and there is some nice topographical detail inland. An inset at top extends the main map, showing the entirety of the Aleutian Islands.
