The Yellowstone-Grand Teton region was not officially discovered and its scenic marvels were not publicly proclaimed until the 1870’s, beginning with the Washburn-Langford-Doane expedition. For thirty years before, from 1841 to 1869, this region was a Paradise Lost, rarely visited by white men. But for thirty years before that, or from 1807 to 1840, this region had hundreds of appreciative visitors. These were the Rocky Mountain fur trappers. While searching for the golden-brown fur of the beaver, destined for the St. Louis market, these adventurers thoroughly explored this fabulous region. Although news of their discoveries received scant public notice back in the settlements, or was discounted as tall tales, to them belongs the honor of being the first actual explorers of these twin parks.
