The Mount Blue Sky renaming + the cultural context
In 2024, the US Board on Geographic Names formally renamed Mount Evans to Mount Blue Sky. The renaming was led by Cheyenne and Arapaho nations and approved after years of advocacy. The byway name has shifted in USFS signage and in newer maps. Older maps and signage may still use 'Mount Evans.'
The renaming reflects a broader process across the West — geographic features named for historical figures with violent legacies toward Indigenous communities are being reconsidered. Mount Evans was named for John Evans, a territorial governor whose actions contributed to the Sand Creek Massacre of 1864.
For travelers, the road is the same road. Use either name in conversation and on navigation apps; both still resolve. The official USFS signage now uses Mount Blue Sky.
Indigenous geographic renaming
Acknowledging the Cheyenne + Arapaho renaming
The Mount Blue Sky name was selected by the Cheyenne and Arapaho nations whose ancestral lands include the mountain. The name reflects ceremonial significance and replaces a name that honored a colonial-era governor with documented involvement in the 1864 Sand Creek Massacre.
Travelers visiting the mountain are welcomed but invited to acknowledge that this is sacred ground for the Cheyenne and Arapaho. Leaving no trace, observing wilderness rules, and respecting cultural significance is appropriate behavior.
