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.

C75 field & runways

Marshall County, Lacon, Illinois. Field elevation 584 ft. Non-towered (NON-ATCT). Magnetic variation 1.0°W on record, 2.8°W 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 0.042°/year west — about 1° every 24 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
13	128.3°	131.1°	matches	4,003 ft	ASPH
18	181.3°	184.1°	matches rule gives runway 19 in ~20 yr	2,199 ft	ASPH	left
31	308.3°	311.1°	matches	4,003 ft	ASPH	right
