Find "Trail Canyon" coming out of the Par Range in the center of the map (a dirt road is shown coming down the fan of Trail Canyon). Why are the contours showing the Trail Canyon alluvial fan so irregular (many tiny zigzags)? (Hint: What surface features of the fan are these zigzags showing?)

Please help me with these questions. I have added the map also.
4. 5. Find "Trail Canyon" coming out of the Panamint Range in the center of the map (a dirt road is shown coming down the fan of Trail Canyon). Why are the contours showing the Trail Canyon alluvial fan so irregular (many tiny zigzags)? (Hint: What surface features of the fan are these zigzags showing?) How deep is the gully cut by the ephemeral stream (shown with a dashed blue line) that flows down the Trail Canyon alluvial fan where it crosses the "sea level" contour at the bottom of the fan? (You can estimate the depth of a valley or gully on a slope by comparing the size of the "V" in the contour line to the overall spacing of contour lines on that slope. For exam- ple, if the V extends up to the position of the next higher contour line on the slope, the valley is about one contour interval deep; if it extends halfway to the next higher contour line, the valley is about one-half contour interval deep, and so on.) feet deep
