RANCHO SAN MARCOS
TOMBSTONE, AZ
74AZ is the identifier for Rancho San Marcos, a privately owned, non-towered airport in Tombstone, Arizona. The airport is served by a single runway, 18/36, which measures 4,800 by 50 feet with a dirt surface.
Operations are VFR only, as no instrument approach procedures are published for the field. The strip is non-towered and has no published frequencies; pilots keep their own separation under see-and-avoid procedures. No fuel service is listed for the field. As a private-use facility, it is not open to transient traffic without prior permission.
The field rests at 4,353 feet above mean sea level. At that elevation, density altitude is a routine consideration in warm weather.
