What topographic evidence (other than the glaciers entering the water) suggests that the Tracy Arm is a fjord?
The question is based on Map T-14, the “Sumdum (D-4), Alaska” quadrangle (scale 1:63,360; contour interval 100 feet). The map shows two glaciers entering the “Tracy Arm.” The Tracy Arm is a fjord just south of Juneau, Alaska (see Exercise 49 for a brief discussion of fjords). The “Sawyer Glacier” enters the Tracy Arm from the north and the “South Sawyer Glacier” enters the Tracy Arm from the southeast (57°52'27"N, 133°10'33"W).
