All along the high ridges and basins of the eastern slope of the North Cascades, lives a distinctive tree. The alpine larch (Larix lyallii) eeks out its existence at the very edge of tree-line in these mountains, acting as the gateway to the alpine above and the immense trees which characterize lower elevations in these mountains. Larch trees are the only conifer tree in the world that has deciduous needles and each fall the brilliant gold of these trees lights up the crisp fall air in the high mountains.
