Rosario West Airport

No official reason for the closure has been published. Given its nature as a small, unpaved, and remote airstrip, the most probable cause is economic abandonment. It was likely a private airstrip serving a specific local entity, such as a large ranch, agricultural operation, or mining prospect, that either ceased operations or no longer required air access. The existence of another airstrip (Rosario de Tesopaco Airstrip, ICAO: MM29) closer to the town may have also rendered it redundant.

The site is completely abandoned and defunct. The former runway is still visible on satellite imagery but is in a state of severe disrepair. It is unmaintained, heavily overgrown with desert scrub and vegetation, and bisected by informal dirt tracks. The area is not suitable for any form of aviation and appears to have reverted to undeveloped rural land.

Rosario West Airport had no major national or regional significance. Its importance was strictly local. As a basic dirt airstrip with no terminal or hangar facilities, it served private general aviation. Operations would have been limited to light, single-engine aircraft (e.g., Cessna, Piper) capable of landing on unprepared surfaces. Its primary functions were likely providing air access for local ranchers, supporting agricultural activities like crop dusting, or facilitating transport for personnel and supplies related to mining exploration in this remote region of Sonora.

There are no known or published plans to reopen Rosario West Airport. The prospects for its revival are extremely low to non-existent. Factors contributing to this include its advanced state of decay, its remote location, the lack of infrastructure, and the presence of the alternative Rosario de Tesopaco Airstrip (MM29) that serves the municipality's needs for basic aviation.
