Dimensions Height: 6-15 m. (20-50 ft.)
Diameter: 0.3-0.6 m. (1-2 ft.).


Habitat Mountains.


Range Northwest, Southwest, California, Western Canada, Rocky Mountains.


Discussion Trees may have a single-stemmed or a clumped, multi-stemmed habit. Site differences and Clark's nutcracker seed-caching behavior may affect frequency of clumping. Female cones located mostly at the tops of the upswept branches, readily recognizable from the air, probably an adaptation to encourage seed foraging by Clark's nutcrackers. Purple cast of mature cones may further aid Clark's nutcrackers in finding ripe seed.
