Flatiron Mountain Ski Trail is intermittently groomed. Ski or snowshoe up to Rainbow Lake road taking a right at road junctions. The road switchbacks near the top, and trees are very sparse so it is possible to ski up and follow the ridge. Look ahead to the edge of the logged area for the point at which there are few trees between it and the open ridge. Ski the open ridge to the summit. A circle trip may be made by skiing down through open trees between the summit and clearcut, skiing south to the lower road or clearcut. Parking capacity for 10 vehicles. Motorized vehicles prohibited.Length: 2.5 km of most difficult trail Trail Begins: Rainbow Lake-Pipe Creek RoadsTrail Ends: LoopArea Map: Kootenai National Forest Visitors Map USGS Map1: FlatironTownship 33N, Range 31W, Section 6
