No FAA diagram publishedThe FAA does not publish an Airport Diagram (APD) for KSMN — most non-towered fields, heliports, seaplane bases, and private strips fall here. Below: aerial imagery showing the actual field, runways, taxiways, and surroundings.

Runways at KSMN
2 runway ends on file. Longest: 5,510 ft. Max gradient: 0.15%

Source: in-app airport database (runway lengths + headings), OurAirports for surface, width, lighting. Gradient computed from FAA NASR runway-end elevation deltas (the published RWY_GRAD field is empty in 99.99% of NASR rows; we derive it from the elevations the FAA does publish).
