**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, 114°31'02"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 a smaller scale. On this small map, trace the length of all first-order streams with blue lines, the length of all second-order streams with red lines, and the length of Eds Creek (as a third-order stream) with a green line. If you don't 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?

3. 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.

**Stream Order | Elevation Drop (feet) | Length (miles, to nearest 0.1 mile) | Gradient (feet/mile)**

Answer :

The question asks about the natural feature associated with the Eds Creek drainage basin that the unimproved dirt road along "Ed's Ridge" follows. By examining the map and stereogram, we can determine the corresponding natural feature.

What natural feature does the unimproved dirt road along "Ed's Ridge" roughly follow in the Eds Creek drainage basin?

By examining the map and the stereogram, it can be observed that the unimproved dirt road follows the elevated ridge line running parallel to Eds Creek. The road is located on higher ground, indicating that it follows the natural feature of the ridge associated with the Eds Creek drainage basin.

2. Stream patterns and order classification in the Eds Creek drainage basin on Map T-3.

(a) The number of first-order streams shown on the small map can be determined by tracing the blue lines representing the length of each segment. Counting these segments reveals the total number of first-order streams.

(b) Similarly, the red lines on the small map represent the length of the second-order streams. Counting these segments will provide the total number of second-order streams in the Eds Creek drainage basin.

The stream patterns and order classification can be identified by tracing the segments on the small map. First-order streams are the smallest tributaries that join together to form second-order streams. By following the blue lines, we can count the number of first-order streams. Similarly, the red lines represent second-order streams, allowing us to count their number.
