The McBride Glacier is a 20 kilometer-long glacier in Glacier Bay National Park and Preserve in Alaska .
geography
The glacier has its nutrient area on the southern flank of the Takhinsha Mountains in the Alsek Ranges . From there, the glacier, which is one kilometer wide on average, flows in a predominantly south-south-west direction and ends at an eastern side bay of Muir Inlet , a fjord of Glacier Bay .
Glacier development
The McBride Glacier steadily retreated over the course of the 20th century. Until the early 1960s, the McBride Glacier was still a tributary glacier of the Muir Glacier . The ice front reaches an average of 60 m above and 80 m below the waterline. The ice speed is estimated at 1000 meters per year. The annual retreat rate of the glacier was 100 m in the early 2000s.
Naming
The glacier was named by Harry Fielding Reid after H. McBride, a participant on his excursion to Glacier Bay in 1890.
