EXERCISE 39 PROBLEMS-PART I The following questions are based on Map T-3, the "Deer Peak, Montana" quadrangle (scale 1:24, 000; contour interval 40 feet), and Figure 39-3, a stereogram of the same area showing the drainage basin of Eds Creek (46 54 26"N, 11431'02"W). 1. The unimproved dirt road (the double-gray and white line) along "Ed's Ridge" roughly follows which natural feature associated with the Eds Creek drainage basin? 2. The stream pattern within the drainage basin of Eds Creek on Map T-3 is reproduced at right at a smaller scale. On this small map, trace the length of all first-order streams with blue lines, b2 the length of all second-order streams with red a lines, and the length of Eds Creek (as a third-I< order stream) with a green line. If you don't 4 have colored pencils, number each segment as 1, 2, or 3. . (a) How many first-order streams are shown? (b) How many second-order streams are shown? ength op a 4 b are the s0 Using Map T-3, determine the gradients of the two first-order streams labeled "a" and "b" on the map above, the second-order stream labeled "c" on the map above, as well as Eds Creek after it has become a third-order stream. Determine stream length to the nearest 0.1 mile (take your measurements from Map T-3, not the small map above) using the graphic scale provided.
