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.

F98 field & runways

Yoakum County, Plains, Texas. Field elevation 3705 ft. Non-towered (NON-ATCT). Magnetic variation 7.0°E on record, 5.9°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 0.077°/year west — about 1° every 13 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
17	180.4°	174.6°	matches rule gives runway 18 in ~5 yr	3,924 ft	ASPH	left
21	220.2°	214.3°	matches rule gives runway 22 in ~9 yr	5,001 ft	ASPH
3	40.1°	34.3°	matches rule gives runway 4 in ~9 yr	5,001 ft	ASPH
35	0.5°	354.6°	matches rule gives runway 36 in ~5 yr	3,924 ft	ASPH	left
