Unknown — not enough evidence to call a runway

We don't know, and saying so beats guessing. No D-ATIS feed here — a voice ATIS/AWOS may exist; check the frequency. No ADS-B traffic data available. Weather observation is 1431 minutes old — treat with caution. Wind variable at 4 kt — no directional preference.

KVMR field & runways

Harold Davidson Fld, Vermillion, South Dakota. Field elevation 1147 ft. Non-towered (NON-ATCT). Magnetic variation 3.0°E on record, 2.7°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 0.062°/year west — about 1° every 16 years — which is why runway numbers eventually stop matching their pavement.

Runway data from the FAA NASR 01 Oct 2026 cycle. Where NASR locates both thresholds, the true heading is the bearing between them rather than NASR's whole-degree alignment. Magnetic is that heading against *today's* declination from WMM2025, not the field's variation of record — so it can differ from the chart by the gap between the two shown above. The number painted on the runway is the one ATC uses.
Runway	True	Magnetic	Number	Length	Surface	Pattern	Notes

30	306.1°	303.5°	matches rule gives runway 31 in ~25 yr	4,105 ft	CONC	left
