That puts the light piston pattern near 2,075 ft MSL based on the field elevation, but confirm before you fly. The airport is closed during winter months, so check current status before planning an arrival.

Published remarks matter here. Radio control aircraft operate on and around the airport. T-hangars sit adjacent to the runway. Runway 17 has a lighted pole 495 ft from the displaced threshold on the right side. Runways 17 and 35 are marked with yellow cones at the corners and edges. There are no on-field FBOs listed, so contact the airport operator directly or call the field on CTAF for current service details. For clearance delivery, use Des Moines Approach at 515-974-8016. If that office is closed, Minneapolis ARTCC handles clearance delivery at 651-463-5588.
