That puts the pattern at 3,909 ft MSL based on the listed field elevation. The runway environment needs a close look before arrival. Trees line the east side of the runway for much of its length. Runway 31 has trees close in both approach surfaces within 180 ft of the runway ends. Runway 13 has a terrain dropoff, brush and a creek just beyond the end. Runway 31 also has a terrain dropoff and brush beyond the end. The runway can be muddy when wet.

No on-field FBOs are listed. Plan to verify services with the airport operator or the FBO directly by phone before you go. Published remarks also note vehicles and horses in the vicinity of the runway. Clearance delivery is handled through Salt Lake ARTCC. The airport is a simple backcountry-style strip with a few real hazards near the pavement. A first-time pilot should treat the departure and landing ends with extra caution.
