48S field & runways
Harlem, Harlem, Montana. Field elevation 2643 ft. Non-towered (NON-ATCT). Magnetic variation 16.0°E on record, 10.5°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 0.094°/year west — about 1° every 11 years — which is why runway numbers eventually stop matching their pavement.
