Prairie and peregrine falcons, Canada geese, and various species of hawks and owls inhabit this 25,000-acre refuge. Trumpeter swans also occasionally use the area. Within or near the refuge there are homestead and ranch sites, Oregon Trail crossings, and ferries that cross the Green River, as well as the spot where Jim Bridger and Henry Fraeb built a trading post in 1839. Visitor information and restrooms are available during daylight hours.
