Chimney Rock is a prominent geological rock formation in Morrill County in western Nebraska. Rising nearly 300 feet above the surrounding North Platte River valley, the peak of Chimney Rock is 4,226 feet above sea level. During the middle 19th century it served as a landmark along the Oregon Trail, the California Trail, and the Mormon Trail, which ran along the north side of the rock. It is visible for many miles from the east along U.S. Route 26.
Chimney Rock was designated a National Historic Site on August 9, 1956 and is a National Park Service affiliated area. It is maintained and operated by the Nebraska State Historical Society. Chimney Rock and Independence Rock further west are probably the most famous features along the Oregon Trail
The Ethel and Christopher J. Abbot Visitor Center features museum exhibits and a video about pioneers and the migrations in the West, as well as a gift shop.
On March 1, 2006, the Nebraska State Quarter was released. The quarter features a covered wagon headed west past Chimney Rock, memorializing Nebraska's role in westward migration.
