Not illustrated. 1912 edition. Excerpt: ...represented on Plate II on Sections B-B, C-C and D-D; and a north-south direction on Section F-F. Mounts Lincoln, Cameron And Bross General Description--The highest part of the territory embraced in this survey is that covered by these three summits. They really form one massif that stands out separated from the main range by the deeply eroded valleys of the Platte River and Buckskin Gulch, and is partially connected by the saddle between Mounts Lincoln and Democrat. The three peaks that form the highest part of this high mountain massive lie close together, the most distant, Lincoln and Bross, being not over a mile and a half apart; Cameron forming virtually a second summit on Mount Lincoln. Lincoln and Cameron are over 14,200 feet, and Bross only a hundred feet lower. A great, deeply cut valley, with steep, mountainous sides, called Cameron Amphitheater, deeply dissects this massive on the east side and nearly cuts it in two. This valley lies between Bross and Lincoln, and has cut back so far that only a very narrow ridge is left connecting Bross with the two other summits. Nearly the whole of this mountain mass--except the eastern foothills, covered mostly with glacial drift--lie above timber line. On the north and west, and on the sides of Cameron Amphitheater, the excessively steep slopes and the heavy covering of rock debris render geologizing extremely difficult. The more gentle eastern slope, on the other hand, is much more readily accessible and, except for the equally heavy covering of wash, not particularly difficult to map.
