Greenhorn Valley Airport

The exact official reason is not documented. However, the most likely cause was economic, driven by the sale of the land for more profitable use. The area experienced growth, and the property was subsequently sold and re-zoned for residential development, a common fate for small, privately-owned airfields in desirable locations.

The site has been converted into a residential housing subdivision. The faint outline of the former north-south runway is still visible on satellite imagery as a wide, grassy corridor between homes. Several houses have been built directly on the former airport grounds. In a nod to its aviation past, the streets in the development have names like 'Kitty Hawk Drive' and 'Lindbergh Circle'.

Greenhorn Valley Airport (formerly FAA identifier: CO57) was a privately-owned, public-use airport established between 1978 and 1981. It served the general aviation community of the Greenhorn Valley, including the nearby towns of Rye and Colorado City. Its primary function was to provide a local landing spot for recreational pilots and small private aircraft. The airport featured a single 4,200-foot unpaved gravel/dirt runway (17/35). It was a basic facility, offering aircraft tiedowns but no fuel services, catering to Visual Flight Rules (VFR) operations. The identifier 'US-11185' is a non-standard code found in some third-party databases, not an official ICAO or FAA designation.

There are no prospects for reopening the airport. The land has been permanently repurposed for residential use with multiple private homes and infrastructure built directly on the former runway and taxiway areas, making a return to aviation operations impossible.
