Cavanaugh Bay Airport sits in Coolin, Idaho. The field elevation is 2,484 ft MSL. It has one runway, 15/33. The longest runway is 3,100 ft of turf. This is an uncontrolled field with no tower. CTAF is 122.9.

No ILS approaches are published here. The pattern altitude is not published, so use standard light piston pattern planning at 1,000 ft AGL unless the current Chart Supplement says otherwise. The airport has a magnetic variation of 20°. Runway 15/33 uses white rocks to mark the edges and thresholds. The runway ends do not have line of sight to each other.

This is a field where you want to brief the terrain and the runway environment before arrival. Both runway ends have trees that affect approach or departure. Runway 15 has several close-in obstacles near the threshold area, including trees, a road and a building. Sprinklers can be on the runway. No winter maintenance is provided. Heavy snowmobile activity also occurs in winter. Seaplane operations are conducted in the bay north and adjacent to the airport. Monitor CTAF for that traffic. A caretaker is on site during summer months. For clearance delivery, contact Seattle ARTCC at 253-351-3694.
