7K7 field & runways
Graham Fld, North Sioux City, South Dakota. Field elevation 1109 ft. Non-towered (NON-ATCT). Magnetic variation 7.0°E on record, 2.3°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 | True | Magnetic | Number | Length | Surface | Pattern | Notes |

| 33 | 337.3° | 334.9° | matches rule gives runway 34 in ~1 yr | 3,233 ft | CONC | left |
