4U6 field & runways
Circle Town County, Circle, Montana. Field elevation 2441 ft. Non-towered (NON-ATCT). Magnetic variation 9.0°E on record, 8.6°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 0.083°/year west — about 1° every 12 years — which is why runway numbers eventually stop matching their pavement.
