Trout Run Drainage Basin: Complete items a through h below. a. This map is contoured in feet. The contour interval is: feet. b. The elevation of point X is: feet. c. The elevation of point B is: feet. d. The elevation of point A is: feet. e. The distance from A to B is: mile(s). f. The gradient from A to B is: feet per mile. g. Lightly shade or color the area inside each closed contour that represents a hilltop, then draw a dashed line to indicate the drainage divide that surrounds Trout Run drainage basin. h. Trout Run flows (drains down hill) in what direction? Imagine that drums of oil were emptied (illegally) at location X above. Is it likely that the oil would wash downhill into Trout run? Explain your reasoning. B. Refer to the topographic map of the Lake Scott quadrangle, Kansas (FIGURE 11.4). This area is located within the Great physiographic province and the Mississippi River Drainage Basin. The Great Plains is a relatively flat grassland that extends from the Rocky Mountains to the Interior Lowlands of North America. It is an ancient upland surface that tilts eastward an elevation of about 5500 feet along its western boundary with the Rocky Mountains to about 2000 feet above sea level in western Kansas. The upland is the top of a wedge of sediment that was weathered and carried eastward from the Rocky Mountains by a braided stream system that existed from Late Cretaceous to Pliocene time (65-2.6 Ma). Modern streams in western Kansas drain eastward across the Great Plains and cut channels into the ancient upland surface. Tiny modern tributaries merge to form larger streams that eventually flow into the Mississippi River. You can view this in Streamer, go http://nationalmap.gov/streamer/webApp/streamer.html and click on the "Go to Map" panel. Then click on the " Downstream" tab, zoom in to any stream in western Kansas (KS), and click on the stream. The red line will show how

Explanation / Answer

a) contour interval = [high point-low point]/number of intervals

     = [200-100]/5

= 20 feet

b) X = 200+20+20

   = 240 feet

c) height of B = 100 ft because it lies on same contour as marked as 100 feet

d) height of A = 180 feet because 200-20=180
