JESSICA FLOCK – THE POWELL 150 EXPEDITION
Friday, October 2nd, 6-7pm, in Green River, Wyoming at Expedition Island Park & Pavilion, 475 South 2nd East. Hosted by Wyoming Public Media. Open to the public.
Jessica Flock, ACHS Past President, will give a special presentation about her participation in the 150th anniversary expedition down the Colorado River, commemorating the 1869 river trip led by John Wesley Powell. The 1869 expedition, which charted unknown territory from Wyoming to the Pacific, began in Green River. John Wesley Powell, a fascinating and notable figure in American history, was a Civil War veteran, explorer of the American West, and second director of the United States Geological Survey (USGS). During Jessica's presentation, she will discuss the importance of the Colorado River Exploring Expeditions of 1869 and 1871, juxtaposed with the Sesquicentennial Colorado River Exploring Expedition in 2019.
Wyoming Public Media’s opening reception that evening in Green River will feature a photo exhibit celebrating the winning entries from its Wyoming’s History Through Listeners’ Eyes photo contest. These vibrant images—captured by listeners from across the state—offer unique perspectives on Wyoming’s landscapes, communities, and heritage. The photo display will then be at the Sweetwater County Historical Museum for the month of October.
