Sierra Lodgepole Pine (Pinus contorta var. murrayana (Grev. & Balf.) Engelm.), of the Cascade Mountains of southwestern Washington and western Oregon, the Sierra Nevada of central California, south to northern Baja California, is a tall (usually 70-80 ft., can be much taller), narrow tree with thin, scaly bark; relatively broad, yellowish green to dark green needles that are twisted; and symmetrical, lightweight cones opening at maturity and shedding within a few years. It is a variety of Pinus contorta. It can take several years for the cones to reach maturity and open. The crown will be especially narrow if the tree is growing in crowded, forest conditions. With more space, the crown will enlarge and appear heavier and more open and spreading.
