Kootznahoo Inlet is located on the eastern shore of Chatham Strait in the U.S. state of Alaska.
The island is inhabited by about 1500 brown bears, the largest number recorded anywhere on the earth.
The general elevation of the surrounding land is less than 100 feet (30 m), and the channels seldom exceed 20 fathoms in depth.
Volcanic rocks are noted in the area as seen from the sediment deposits at the inlet.
Later, Angoon people also used this inlet and built a village here for fishing, hunting and trapping.
