In the course of compilation, between 1810 and 1814, Clark must have sent a redrawing of the route of Colter’s journey.[358] By way of review, let it be remembered that Colter reached St. Louis in May of 1810. He called on Clark and evidently presented several sheets of trapper map to him. This was the material which depicted his journey of 1807, and it seemed to be highly appreciated by Clark. That it was given preference by Clark over the contemporary exploration of Zebulon M. Pike simply substantiates the belief that Colter’s journey made a profound impression upon Clark at that time.[359] On December 20, 1810, Clark apparently sent the original Colter sheets, or properly redrawn copies of them, to Nicholas Biddle. Clark also inserted, or superimposed, two rivers upon the Colter drawing. They were Clarks Fork and Bighorn rivers. It is important to remember that Clark had full confidence in Colter’s representation of his journey at this time, that is, December, 1810. The following year Andrew Henry returned from his exploration of the Madison and Snake river regions. He had seen only ordinary country. This report seems to have destroyed Clark’s belief in Colter’s story of marvels. Not wishing to deceive anyone by the delusions of a deranged trapper’s mind, Clark apparently directed Samuel Lewis to retain Colter’s east plat, that is, the Buffalo Bill country, but suppress the western section, the Yellowstone Lake region. In lieu of Colter’s depiction of the western loop of his figure eight Clark evidently sent the draft that now appears on the Map of 1814.
