About Colorado UAP sightings

Colorado's San Luis Valley has among the highest per-capita UAP sighting rates of any region in the United States. Cheyenne Mountain Complex and Schriever Space Force Base place Colorado at the center of U.S. military space operations, while the state's high elevation and clear mountain air provide exceptional sky visibility.

In 2012, footage of an unidentified daylight object over Denver was broadcast nationally and sparked significant public debate. The state's UAP community is among the most organized in the country, with several established research groups.

Eastern Colorado's flat plains and dark skies produce a disproportionate share of rural reports, while the Front Range urban corridor from Fort Collins to Pueblo shows predictably elevated population-driven counts.
