Iron Cap Mountain is a 6,347-foot peak in Washington’s Alpine Lakes Wilderness, near Dutch Miller Gap and just west of the Cascade crest. Managed within Mount Baker-Snoqualmie National Forest, it rises steeply above the Middle Fork Snoqualmie River valley and drains toward both the Snoqualmie and Foss river systems. Small remnants of ice remain on its slopes, and its marine west coast climate brings heavy precipitation, dense winter snow, and avalanche danger, while summer offers the best conditions for viewing or climbing. The mountain’s rugged character reflects millions of years of tectonic, volcanic, terrane-building, and Pleistocene glacial processes in the North Cascades.
