What does an arborist do on vacation? Look at trees of course! We just got back from a trip to Lake Quinault where, among other huge specimens, we saw the world's largest Sitka Spruce, clocking in at 58-11" circumference, and 191' tall. We also visited the world's largest Western Red Cedar, clocking in at 19.4' in diameter and 178' tall. This area receives an average of 144" of rain per year and is home to many giant trees.
