On the First Expedition (1869), Powell's party camped near the mouth of Ashley Creek while the Major boat proceeded downstream to the Uintah [Duchense] River -- the next tributary to the south where a overland route between Denver and Salt Lake City crosses the Green River. At the crossroads, Powell and his companions continued 40 miles west to the Uintah Ute Agency to collect and send mail, ship fossils, and purchase more food for the journey. The remaining men trailed behind hunting, fishing, and exploring the river valley, waiting for the Major's return near the confluence of the Duchense and Green Rivers. They reported having had a miserable experience dealing with mosquitoes waiting for Powell's return a week later. They then departed downstream into uncharted territory along the Green River: the Desolation Canyon wilderness.

On the Second Expedition (1871) Powell left at Ashley Creek to be with his child-bearing wife, Emma, in Salt Lake City and to troubleshoot problems for the rest of the journey. Powell turned the command over to his brother-in-law "Prof" Almon Harris "Harry" Thompson to lead the expedition downstream. Powell rejoined the Second Expedition in at "Gunnison Crossing" (Green River, Utah) on September 3rd. Click here to continue to the "Desolation Canyon" page.
