It extends 18 miles (29 km) in a northeast direction from Stephens Passage in the Alexander Archipelago, about 12 kilometres (7.5 mi) southeast of Juneau, widening to a basin where discharge from the Taku River and Taku Glacier emerges.
As a result of the rapid movement of the glacier, silting has occurred at the head of the inlet.
However, a clear channel exists between Taku Point and the Norris Glacier moraine, 1.25 miles (2.01 km) wide, with a depth of above 10 fathoms.
A complete preliminary navigational chart, to a scale of 1:10,000, has been prepared by field surveys, to facilitate interested navigators to operate ships to view the glaciers.
