[42]Colter’s first sheet is readily identifiable, and part of another sheet may be segregated with the use of imagination and understanding.
[43]Many writers have failed to identify Gap and Sage as the same creek. They also befuddle Wind and Shoshone rivers. There is no evidence that Colter ever heard the name Bighorn River.
[44]The figure eight results from the fact that he went to the Yep-pe camp, left it, came back, and left it again at the appropriate angles.
[45]In 1941, Paul J. Shamp, a U.S. forester, reported the discovery of numerous petrifications in the vicinity of Pass and Scatter creeks in the Thorofare country. This is the line of Colter’s route.
[46]Colter did not see Southeast Arm of Yellowstone Lake. He probably supposed the Upper Yellowstone flowed into South Arm. Hence, his conception of Yellowstone River would have been ten miles farther west than it is. Neither could he have visualized the serpentine character of Snake River, since he knew it at only one place.
[47]Colter may have reached Chicken Ridge by Fishhawk, Mountain, or Lynx creeks or via Falcon, Mink, or Crooked streams. It must be remembered that this map sheet has been much messed up. It is impossible to know what has been erased; yet, enough of Colter’s map remains to provide a logical basis for the above itinerary. It is relatively unimportant which creeks he negotiated to reach Chicken Ridge. The vitally important fact is that he drew a sketch of South Arm from that angle which added to the Thumb makes an accurate map of what a trapper would have seen of Yellowstone Lake.
[48]J. Neilson Barry has made the most intensive study of the Map of 1814. It is his opinion that Colter drew other map sheets besides the one of the Buffalo Bill country. He also has hope that these sheets may be discovered among the Lewis-Clark-Biddle papers.
[49]In E. Willard Smith’s journal entry for December 20, 1839, there is an item that suggests a possible clue to mystery of Colter’s petrified fish story: “There is a story told by an Arapahoe Chief of a petrified buffalo standing in the lake ... in a perfect state of preservation, and they worship it as a great medicine charm.... Nothing would induce this Indian to tell where this sacred buffalo is to be found. Great presents were offered him in vain.” It is possible that Colter saw something he was not free to divulge. See “An Excerpt From the Journal of Willard E. Smith,” Annals of Wyoming, XV, 3 (July, 1943), 287-97.
[50]John G. White, “A Souvenir of Wyoming,” Vol. I, p. 56. This is a fine work of research in manuscript. It was written in 1916. There are five volumes in the Yellowstone Park library. The time of this Indian episode was in the autumn of 1808.
