1D7 field & runways
The Sigurd Anderson, Webster, South Dakota. Field elevation 1858 ft. Non-towered (NON-ATCT). Magnetic variation 7.0°E on record, 3.1°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 0.058°/year west — about 1° every 17 years — which is why runway numbers eventually stop matching their pavement.
