Beyond the known facts of Colter’s journey in 1807, the Map of 1814, and the “Colter’s Hell” legend, there is a complete hiatus, or vacuum. However, the Map of 1814 is certainly a tangible thing; let it tell its own story: It is known that William Clark had a friend in Philadelphia named Nicholas Biddle who arranged for the publication of _The Lewis and Clark Journals_. In order to properly depict the journey, Mr. Biddle secured the services of a prominent Philadelphia cartographer named Samuel Lewis. Twice in 1810 Clark sent sheets of map material to Mr. Biddle.[352] John Colter reached St. Louis in May, 1810. It is certain that he called upon Clark and gave him information, if not sheets, depicting his famous journey of 1807. This data was undoubtedly sent on to Mr. Biddle, either as Colter drew it or as it was accurately redrawn by Clark. At least one of Colter’s sheets was incorporated in the final Map of 1814.[353] The first, or eastern prairie, side of the Colter plat traced his journey up Pryors Fork, about fifty miles west of Fort Manuel, through Pryors Gap. Then he crossed over to Clarks Fork, which he ascended, probably to Dead Indian Creek. From this creek Colter crossed over a divide to the North Fork Shoshone River where he first smelled sulphur. This he called Stinking Water River, most probably referring to the present De Maris Mineral Springs near Cody, Wyoming. On Stinking Water River he encountered the “Yep-pe Band of Snake Indians 1000 souls.” This was evidently a clan of the Crow tribe. From these Yep-pe Indians, denizens of both prairie and mountain, he undoubtedly learned of the Yellowstone geysers and other marvels. This accounts for his side trip which brought him back to the Yep-pe camp. It is likely that some of these Indians directed Colter along another route in returning to Manuel’s Fort. Obviously they went down the North Fork Shoshone, or Colter’s Stinking Water River, to its junction with Shoshone River. This, he followed to Gap Creek (now Sage Creek) which he ascended to Pryors Gap.[354] By this alternate route Colter again reached Pryors Fork where he crossed over to return to Fort Manuel.
