Van Effen Fld sits in Rock, Michigan. The field elevation is 970 ft MSL. It has one runway, 12/30, which is 2,600 ft of turf. There is no control tower. CTAF is 122.9. No ILS approaches are published here.
The published pattern altitude is not listed. Use the standard 1,000 ft AGL pattern unless the current Chart Supplement says otherwise. Runway 12 and Runway 30 both have displaced thresholds marked with yellow cones. Both approaches also carry a 20 to 1 obstacle clearance slope to the displaced threshold. That makes a stabilized approach important, especially on a short turf strip.
There are no on-field FBOs listed. Contact the airport operator directly before arrival if you need local services. Published remarks also note deer, birds and other wildlife near the runway. There is no snow removal at this airport. For clearance delivery, contact Minneapolis ARTCC at 651-463-5588. Pilots planning a first visit should review the current Chart Supplement for any updated local procedures. Then brief the turf surface, the displaced thresholds and the wildlife risk before departure.
