Forests of Crater Lake National Park
Western Hemlock (Tsuga Heterophylla)
On the Rogue River side will be found western hemlock (Tsuga heterophylla) in canyons, along streams, and on shaded north slopes (fig. 21). It is a rather large tree, with smooth, round, red-brown trunks, and light open crowns of delicate, yellow-green foliage. Its cones are much smaller but are similar in shape to those of mountain hemlock. It is a fairly abundant tree at middle altitudes on the western slopes of the Cascades, and in the Coast Mountains forms a considerable part of the heavy forests of Oregon, Washington, and British Columbia.
