Instrument procedure pattern

All three approaches at Lemhi County serve a single end of runway 17/35, concentrating published instrument access in one direction rather than dividing it between both ends. The two RNAV (GPS) procedures provide most of that coverage, while the VOR procedure adds a differently based option. No separate airport diagram is published for the single-runway layout.

Coverage around Salmon

Dillon also has six published charts, giving it comparable coverage by chart count. Challis has only three, making its procedure set distinctly thinner. The Great Falls Sectional adds the wider visual-chart context around Salmon that the airport-specific instrument procedures do not provide.

Is KSMN a towered airport?

No — Lemhi County has no control tower. Traffic co-ordinates on a common frequency rather than with a controller, which is listed in the frequencies table on this page.

Are these KSMN charts current?

They are from the FAA cycle effective 6 August 2026, which is superseded on 3 September 2026. We publish each new cycle on its effective date. They are for flight simulation and reference only — not for real-world navigation.
