Cajón de Onapa Airport

The closure was most likely due to economic reasons and abandonment. Cajón de Onapa was a small, remote, unpaved airstrip. Such airfields in rural Mexico are typically private and built to support specific activities like mining, large-scale ranching, or agriculture. The closure likely corresponds with the cessation of the economic activity it was built to serve, or it became obsolete due to improved road access or the use of the larger, paved Sahuaripa Airport (ICAO: MMSA) located approximately 40 km to the northwest.

The site is an abandoned airstrip. Current satellite imagery shows the faint outline of the ~1,000-meter dirt runway, which is no longer maintained and is being slowly reclaimed by desert vegetation. There are no remaining buildings, hangars, or any aviation infrastructure on the site. The area is remote and undeveloped, and the former airstrip is not being used for any other purpose.

Cajón de Onapa Airport was a minor general aviation airstrip (aeródromo). Its significance was purely local, providing essential air access to a remote, mountainous region of the Sierra Madre Occidental. It primarily handled light, single-engine, STOL (Short Takeoff and Landing) aircraft. Operations would have included transporting personnel, supplies, and equipment for nearby mines or ranches, as well as private recreational flights. The ICAO code 'MX-2507' is a non-standard, locally assigned identifier used in Mexico for small or unofficial airfields, confirming it was not a public commercial airport.

There are no known or published plans to reopen Cajón de Onapa Airport. Given its abandoned state for over a decade, its remote location, and the availability of the superior Sahuaripa Airport (MMSA) for regional needs, any prospect of reopening is extremely low. A significant new industrial or private development in the immediate vicinity would be required to justify the cost of rehabilitating and reopening the airstrip.
