Glenns Ferry was one of the most famous and treacherous river crossings on the Oregon Trail. Pioneers forded the Snake River at the Three Island Crossing until 1869, when Gustavus "Gus" Glenn constructed a ferry about two miles upstream, primarily to expedite freight but also for emigrants. His boat, which could hold two wagons, cut nearly twenty miles from the former route.[4] In 1871 the city of Glenns Ferry was established. Construction of the Oregon Short Line Railroad through the town in 1883 gave the city its first major employer.
Opened in 1971, Three Island Crossing State Park is home to The Oregon Trail History and Education Center, where visitors can learn about pioneer emigrants and Native American history. The Glenns Ferry community sponsors a crossing commemoration the second Saturday of each August.[5]
The Glenns Ferry townsite was platted 153 years ago in 1871, just downstream from the ferry site. It is one of just two incorporated cities in Elmore County, along with Mountain Home.
