Campo Santa Anita Airstrip

No official reason for the closure has been published. However, the most probable cause is abandonment. Factors likely contributing to this include:
1. **Economic Non-viability:** The extreme remoteness and lack of infrastructure would make maintaining a legitimate private or agricultural airstrip costly and difficult.
2. **Cessation of Original Use:** If the strip served a specific ranch or business, that entity may have ceased operations.
3. **Security Concerns:** The Altar region is a known high-activity corridor for drug trafficking. The Mexican military (SEDENA) actively identifies and disables clandestine airstrips ('narcopistas') in this area. While there is no visual evidence of military destruction (like trenching), the strip may have been administratively closed and designated as unusable by authorities to prevent illicit use, or abandoned by its operators due to increased military surveillance.

As of the latest satellite imagery (2023), the site is completely abandoned. The physical outline of the dirt runway is still visible but it is unmaintained, weathered, and being slowly reclaimed by the Sonoran Desert scrubland. There are no buildings, aircraft, or signs of recent activity. The site is not being used for any other purpose.

The airstrip holds no major public or historical significance. It was a private, unpaved, rudimentary landing strip in a remote desert location. When active, it would have handled small, single-engine, high-wing aircraft (like Cessna 206 or similar utility planes) capable of operating from unprepared surfaces. Its operations were likely related to private transportation for a large, remote cattle ranch or agricultural enterprise ('ejido'), which is common for airstrips with such names in rural Mexico. Due to its strategic location, its potential use for clandestine logistics cannot be ruled out, but this is not officially documented.

There are no known plans or prospects for reopening the Campo Santa Anita Airstrip. Given its extreme remoteness, the lack of any supporting infrastructure (roads, power, water), the significant cost required for rehabilitation, and the prevailing security situation in the region, the likelihood of it being reopened for any legitimate aviation purpose is virtually zero.
