Grasmere Airport (U91) sits in Grasmere, Idaho. The field elevation is 5,144 ft MSL. It has one runway, 05/23, which is 2,750 ft long and dirt. There is no control tower. CTAF is 122.9.

No ILS approaches are published here. Pattern altitude is not published, so use the standard 1,000 ft AGL for light piston operations unless the current FAA Chart Supplement says otherwise. With the elevation and the dirt surface, expect a short-field, high-density-altitude kind of airport. Check performance carefully before you go.

Published remarks matter here. Runway 05 has obstacles on the approach path, including a fence, a road and a marked powerline. The runway edges and thresholds are marked with white rocks. The surface may be poor because of livestock, ground vehicles and rodents. No winter maintenance is provided. There is no telephone at the airport. For clearance delivery, contact Salt Lake ARTCC at 801-320-2568. No on-field FBOs are listed, so verify services with the airport operator or call the field directly before arrival.
