Find the word “South” in the label for the “South Sawyer Glacier” (in the east central part of the map). Assume that the rate of movement of this glacier is 9 inches (22 cm) per day (a hypothetical rate). How long would it take the ice to move from the location marked by the “S” in the word “South” to the water of the Tracy Arm? It may be easiest if you determine the distance in inches or centimeters, rather than in feet, miles, or kilometers.
The following questions are 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).
(a) 
(b) Time for ice to move to the Tracy Arm: _____________ years
