Denver, CO, July 22, 2026 —
DENVER – The familiar “mile-high” marker located on the west steps of the Colorado State Capitol is undergoing its fourth relocation. This adjustment is prompted by technological advancements in GPS and improved measurement precision from NOAA’s National Geodetic Survey.
For over 15 years, the National Geodetic Survey has been gathering data to refine the exact elevation of the capitol steps. The move is intended to ensure a more accurate representation of the 5,280-foot elevation above sea level, a distinction Denver proudly holds.
The precise reason for this specific relocation is attributed to the evolution of measurement technologies. Modern GPS systems and geodetic surveys offer a level of accuracy that surpasses previous methods, necessitating the update to the physical marker.
The official dedication ceremony for the newly positioned marker is scheduled for August 1st. This event coincides with the broader celebration of Colorado’s 150th anniversary, marking a significant milestone for the state.
This is not the first time the marker has been moved. Previous adjustments have been made to maintain its accuracy as measurement techniques and data have evolved over time. The initial marker was placed in 1969.
