Cliff Hatfield Memorial Airport (CLR)

Cliff Hatfield Memorial Airport (CLR/KCLR) is a public-use general aviation facility located in Calipatria, Imperial County, California. It is uniquely notable for its elevation, which is approximately 182 feet below sea level, making it one of the lowest-lying airports in the world. The airfield primarily serves as a base for agricultural flight operations, which are critical to the Imperial Valley's massive farming industry, as well as private and corporate pilots visiting this desert region.

The airport is an unattended facility, reflecting its role as a functional regional airfield rather than a commercial passenger hub. There is no traditional passenger terminal building on-site, meaning that facilities such as indoor waiting rooms, check-in counters, and public restrooms are not available. The infrastructure consists of a single paved runway (08/26) measuring 3,423 feet in length, which is designed to support various light and medium-sized general aviation aircraft. Pilots using the airfield are expected to be self-sufficient and to coordinate their flight operations via the Common Traffic Advisory Frequency (CTAF).

Amenities at Cliff Hatfield Memorial Airport are extremely limited, with no on-site services for food, water, or commercial retail. While the airfield provides a vital landing site for regional agricultural sprayers and private aviators, visitors must bring their own supplies and handle their own aircraft needs. Ground transportation into the city of Calipatria is typically arranged through private vehicles or local pre-coordinated pickups, as there are no on-site taxi services or rental car agencies. Despite its sparse facilities, the airport remains an essential part of the agricultural infrastructure of the Imperial Valley.
