In view of these egregious errors it is a monumental mistake to insist, as so many authors in effect have done, that Colter was a human helicopter who hopped all over the Rocky Mountains in connection with his Yellowstone exploration. Actual geography and common sense prove that he could not possibly have made such an extensive journey, particularly so late in the season. Just as certainly, geography and common sense attest that in traveling a normal western loop essential to yield conformity with the map’s figure eight[44] Colter would have seen precisely the type of country the Map of 1814 does not depict, but which, nevertheless, is actually there! A normal half circle would have brought him upon the Upper Yellowstone River, South Fork of Snake River, Yellowstone Lake, and the thermal areas at Thumb of Lake and Hayden Valley. These paint pots, hot springs, and geysers, particularly Dragon’s Mouth and Mud Volcano, satisfy the descriptions he made and easily meet the requirement of the terms on the map, “Boiling Spring,” “Hot Springs Brimstone,” and also Washington Irving’s reference “... of gloomy terrors, hidden fires, smoking pits, noxious streams....” In effect, these areas alone would qualify as “Colter’s Hell.” [Illustration: J.
