Issued weekly during the summer season, monthly during the remainder of the year by the Nature Guide Service. Much of the timber if cut into lumber would run one hundred and fifty to two hundred board feet to the acre and individual trees of three different species reach a diameter of six feet or more and a height of two hundred and fifty feet. Many of these trees growing in dense stands exhibit from one hundred to one hundred and fifty feet of clear bole.
Individual trees contain sufficient material if cut into lumber to build a large size dwelling.
The three largest trees in the Park are the Western Hemlock, Western Red Cedar and the Douglas Fir which by the way is not a true fir or abies but belongs to the genus Pseudotsuga and has no other close relatives. Of the three big trees mentioned the Douglas fir is by far the most important both in size, numbers and quality of wood. It is found from British Columbia southward to Northern Mexico. The finest forests occuring in Washington and Oregon are on the lower slopes of the coast mountains. Douglas Fir is common in the Park up to 3600 feet, sometimes in almost pure stands but often mixed with other species.
