Topographic map: col

The photo on the top shows the cirque that contains Gunsight Lake. The low spot in the center of the cirque headwall is an example of a col. In this photo you are looking toward the southwest. On the map, the camera shows the approximate location where the photo was taken. The col appears on the topographic map as a low spot on the ridge that runs from Mt. Jackson along the dashed black line toward Sperry Glacier. As contour lines cross ridge tops, the contour lines bend (or point) downhill, and in this example that means the contour lines on either side of the col point toward the col. The bottom photo shows the same col from Lake Ellen Wilson; in this photo you are looking toward the northeast.
