yellow pine

They were all clinker built of yellow pine, double fastened with copper nails, clinched over rooves.

Upon the sides of the mountains and extending down into the valley are found beautiful groves of yellow pine timber.

The timber growing in this region is principally yellow pine, spruce, balsam fir, and hemlock; among the bushes I noticed laurel.

Other species are the alpine fir, Douglas spruce, limber pine, and Western yellow pine.

Probably they were the ruins of yellow pine trees that before my day had perished in a forest fire.
