Idaho City USFS (U98) sits in Idaho City, Idaho at 3,920 ft MSL. This is a non-towered field with CTAF 122.9. No ILS approaches are published. The airport has no listed runways in the provided facts, so verify current runway status and usable length with the current FAA Chart Supplement or the airport operator before you go. The published pattern altitude is not listed. Use the standard 1,000 ft AGL pattern only if the current Chart Supplement confirms that is appropriate for your aircraft and the field conditions.

The remarks matter here. Published notes say runway 04/22 edges and thresholds are marked with white rock. The west 700 feet is turf. The rest is gravel. The first 900 feet of runway end 4 is turf, then dirt and gravel. Trees and other obstacles are a real factor on the 04 and 22 approaches. Seventy-foot trees sit left of runway 04 near the end boundary marker. Cataloged obstacles exceed a 45 degree slope. The FAA also recommends landing runway 04 and departing runway 22 when winds allow. No winter maintenance is provided. United States Forest Service helicopter activity can also show up during fire season. There is no telephone on the field. For clearance delivery, contact Big Sky Approach at 208-364-5860 or 208-364-5861.
