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. Wind calm — no directional preference.

3U8 field & runways
Big Sandy, Big Sandy, Montana. Field elevation 2698 ft. Non-towered (NON-ATCT). Magnetic variation 16.0°E on record, 11.1°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 0.098°/year west — about 1° every 10 years — which is why runway numbers eventually stop matching their pavement.
