The Taku Glacier is a 58 km long glacier in the Boundary Ranges east of Juneau , Alaska . It is the largest outlet glacier of the Juneau Icefield .
geography
The Taku Glacier flows into the Taku Inlet , a branch of the Stephens Passage . In Taku Inlet, the glacier meets the Taku River , which it has dammed several times in the course of its history. The resulting reservoir broke through the ice dam for the last time in 1750 and has not been rebuilt since.
Glacier development
The Taku Glacier calved into the fjord until 1948 , since then its front has been on the mainland and it no longer loses mass due to icebergs breaking away. In contrast to the other glaciers of the Juneau Icefield, the Taku Glacier had a positive mass balance between 1946 and 1988 . The mean value of the mass balance during this time was 0.42 meters of water equivalent per year, so the ice thickness had increased by almost half a meter on average over the total area. The mass balance has been negative since 1988; between 1988 and 2006 it averaged −0.14 meters of water equivalent.
Naming
1883 the glacier in honor of Paul Schulze, a president who was Northwest Trading Company , the name Schultze Glacier given. In 1890 it was renamed Foster Glacier after Charles Foster , a former governor of Ohio . However, shortly afterwards the name, which is still valid today and is derived from the name of the Tlingit Indians for the glacier, prevailed.
