Note 112 — Chapter XI · TO HEKLA AND THE GEYSIR IN HAUKADALR.[87] (continued 2)

In 1859, when I passed over the Rocky Mountains, near the headwaters of the Missouri and the Yellowstone, the North American Geysirs had not been invented, nor did we hear a word about them from the backwoodsmen and prairiemen along the line. In fact, the United States Expeditions which surveyed, photographed, and described them, began only in 1868.
