Pinus albicaulis Engelm. Whitebark pine
Whitebark pine is a native of mountainous regions in the western United States. The Mt. Mazama photos at right are at an elevation of about 1.5 mi (2.5 km). Identification: Trees are up to 69' (21 m) tall, with trunks up to 5' (1.5 m) in diameter. Crown may be rounded, irregular, or contorted by harsh winds. Bark is pale gray, appearing whitish from a distance (hence the name). Needles are in groups of five, tending to curve upward, 1-2½" (3-7 cm) long × ¹/₃₂" (1.5 mm) wide, and deep yellow-green. Cones are oval to roughly cylindrical, ⅜-½" (1-1.5 cm) long, and bright red when flowering. Whitebark pines are found near or somewhat below the timberline, in thin, rocky soils. For further information, see the Pinus comparison tables. Online References:
