RWY 26

Big Horn County Airport sits near Hardin, Montana at 3,025.3 ft MSL. It has one runway. Runway 08/26 is 4,491 ft of asphalt, so plan performance with the field elevation in mind. The airport is non-towered. CTAF and UNICOM are both 122.8. No ILS approaches are published here.

Pattern altitude is not published. Use 1,000 ft AGL for light piston operations unless the current Chart Supplement says otherwise. That puts the pattern at about 4,025 ft MSL. The magnetic variation is 10°. Published remarks note that the PAPI and medium intensity runway lights for runways 08 and 26 are activated by the CTAF. That is useful after sunset or in low light. For clearance delivery, contact Billings Approach at 406-255-2798.

There are no on-field FBOs listed in the facts. Contact the airport operator directly before arrival if you need fuel or ramp details. This is a simple field with one runway. The main things to watch are the elevation. The lack of published ILS matters too. The lighting activation method is also worth briefed before arrival.
