CN13 field & runways
Borges - Clarksburg, Clarksburg, California. Field elevation 12 ft. Non-towered (NON-ATCT). Private use. Magnetic variation 16.0°E on record, 12.8°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 0.091°/year west — about 1° every 11 years — which is why runway numbers eventually stop matching their pavement.
