Harlem Airport sits in Harlem, Montana. The field elevation is 2,643 ft MSL. It has two runways. The longest is runway 11/29 at 4,100 ft on asphalt. Runway 15/33 is 1,933 ft on turf. There is no control tower. CTAF is 122.9.

No ILS approaches are published here. Pattern altitude is not published. For light piston traffic, use 1,000 ft AGL as the standard pattern reference unless the current Chart Supplement says otherwise. The airport sits in open country on the Hi-Line, so density altitude can matter on warm days at this elevation. Check performance before you go.

Published remarks matter here. Runway 11/29 has medium intensity lights. The PAPI on runway 29 is activated by CTAF. The terminal building has telephones. The door uses a push-button lock. Runway 15 is marked with white cones, though most cones are missing. Runway 15/33 has large gopher holes and tall grass throughout. That makes the turf runway a poor choice unless you have current field condition info. For clearance delivery, contact Salt Lake ARTCC at 801-320-2568. No on-field FBOs are listed, so verify fuel and services with the airport operator or call the field directly before arrival.
