Larch trees, a type of deciduous conifer, are typically found east of the Cascade Crest throughout Washington's Cascade Mountains, as well as the broader Pacific Northwest and Canadian Rockies. Unlike other conifers, though, larches lose their needle-like leaves each fall. But first, they turn gold, blanketing the mountainsides of their high-altitude homes in a gilded hue. The spectacular vistas and short viewing window create the same foliage-spotting frenzy as the rest of the U.S., drawing huge crowds for Larch Madness season.
