3MT4 field & runways
Maddox Ranch Company, Chinook, Montana. Field elevation 2589 ft. Non-towered (NON-ATCT). Private use. Magnetic variation 16.0°E on record, 10.6°E today.
The FAA's variation of record is the number this field was surveyed against; the second is where north points now, from WMM2025. It is moving 0.095°/year west — about 1° every 11 years — which is why runway numbers eventually stop matching their pavement.
