Chimney Rock National Historic Site

Chimney Rock is a prominent geological rock formation in Morrill County in western Nebraska. Rising nearly 91 m above the surrounding North Platte River valley, the peak of Chimney Rock is 1,289 m above sea level. The formation served as a landmark along the Oregon Trail, the California Trail, and the Mormon Trail during the mid-19th century. The trails ran along the north side of the rock, which remains a visible landmark for modern travelers along U.S. Route 26 and Nebraska Highway 92.
