On July 15, 1806, Captain William Clark and his party rode from the west, following a creek downstream, now called Billman Creek, to the Yellowstone River. Looking south, they saw the Yellowstone River emerge from between the Absaroka Mountains on the east and the Gallatin Range on the west. The Bridger Range lies to the northwest, and the Crazy Mountains to the northwest. Clark wrote that the Roche, or Yellowstone, passes out of a high rugid mountain covered with snow, with narrow bottoms by the mountains, and that the mountain is rocky rugid and holds great quantities of snow. In the Absaroka Mountains, Mt. Baldy looks down on Livingston, Montana and the Yellowstone River.
