El Porvenir (Cumuripa) Airport

The primary reason for closure appears to be economic and abandonment. Private airstrips like this are typically sustained by a specific local enterprise, such as a large agricultural ranch ('El Porvenir' likely refers to the name of the ranch it served) or a business entity. When that entity no longer requires or can afford to maintain an airstrip, it falls into disrepair. There is no evidence to suggest it was closed due to a specific accident, military conversion, or direct government action.

The airport is completely abandoned and non-operational. Recent satellite imagery shows the single asphalt runway is severely degraded, with extensive cracking, weathering, and significant vegetation growth. A dirt track now cuts across the southern end of the runway, making it unusable for any type of aircraft. The land has effectively reverted to its surrounding rural state, likely used for low-intensity ranching or simply left fallow.

El Porvenir (Cumuripa) was a private general aviation airstrip. Its significance was purely local, serving the remote agricultural and ranching communities in the Cumuripa area, east of Ciudad Obregón. Its operations would have consisted of:
- Transportation for ranch owners, managers, and visitors.
- Logistical support for agricultural activities, potentially including crop dusting (fumigación aérea).
- Access for maintenance personnel or officials related to the nearby Presa Plutarco Elías Calles (El Novillo Dam).
It exclusively handled small, private aircraft (e.g., Cessna, Piper) and had no capacity or designation for commercial passenger, cargo, or military operations. The ICAO code 'MX-2331' is an unofficial identifier used in non-governmental databases and flight simulators, not an official code assigned by the International Civil Aviation Organization.

There are no known plans, proposals, or prospects for reopening this airport. The regional air transportation needs are fully met by the Ciudad Obregón International Airport (IATA: CEN, ICAO: MMCN). Given the remote location, the derelict condition of the infrastructure, and the lack of any apparent economic driver, the cost of refurbishment would be prohibitive and without justification. The site is expected to remain abandoned indefinitely.
