Thousand Mile Tree is a pine tree located in Weber Canyon near the community of Henefer, Utah along the Overland Route of the Union Pacific Railroad. In January 1869, graders of the railroad found a similar tree standing next to the line they were constructing, which by coincidence marked the western progress of exactly one thousand miles of road from Omaha, Nebraska/Council Bluffs, Iowa, the eastern terminus of the First Transcontinental Railroad.
