Pruche de l'Ouest
From 12,000 BP to 10,000 BP, the area got a bigger variety of trees, and became a closed forest. The vegetation was similar to today with Alnus rubra (red alder), Picea sitchensis (sitka spruce), Pinus contorta (lodgepole pine), Pseudotsuga (Douglas fir), and Tsuga heterophylla (Western hemlock).
