Resting nearby a raging river just outside Lake Cushman, was this Western redcedar, or Thuja plicata, of the family Cupressaceae. Some defining characteristics of this native plant are scaley needles, small reproductive cones, and red fibrous bark.
This tree should not be confused with true cedars of the family Cedrus. The fall view of this evergreen tree shows it sits by neighboring firs and hemlocks. Lichens and moss cling to its bark, absorbing all of the moisture-rich air.
