Hall of Mosses and Spruce Nature Trails Professional Review and Guide
"Perhaps the most renowned natural attraction of Olympic National Park is its temperate rain forests. Watered by prodigious amounts of rain, giant (make that massive, no, positively enormous) conifers tower up to 300 feet over the forest floor, creating a nearly unbroken canopy of branches and needles. Living exclusively in that high canopy are a host of unusual organisms, such as lettuce lichens, various mosses, and numerous small animals that spend their entire lives in the treetops and are rarely even seen by most people.
At a lower level, shorter (but still quite large) trees, such as big-leaf maples, vine maples, and red alders, fill the available space and are literally covered with club mosses that drape off the branches like thick green hair that is up to 6 feet long. Shrubs, such as salmonberry, crowd into what niches they can find, while numerous ferns, liverworts, mosses, oxalis, and dozens of other plants carpet what is left of the uncovered forest floor. Green is literally everywhere, and it truly is a sight to behold."
