Natural History
The Sol Duc and the other tributaries of the Quillayute River support some of the healthiest stocks of wild winter steelhead trout in the Pacific Northwest, with as many as 19,000 steelhead returning to spawn in some years. There are also large runs of chinook and coho salmon. The lack of glaciers at stream headwaters keeps the consistency of river fish habitats. Of the Quillayute's tributaries, the Sol Duc River is remarkable in its migratory fish diversity and health. It is the only Quillayute tributary that supports spring chinook salmon. It contains sockeye salmon in June and July and so-called summer coho salmon in August and September. Cutthroat trout also spawn in the Sol Duc River.
The Sol Duc River is one of the only rivers of the Olympic Peninsula that supports all five major species of salmon. The upper Sol Duc is a prime coho spawning stream.

Famous quotes containing the words natural history, natural and/or history:
“The use of natural history is to give us aid in supernatural history: the use of the outer creation, to give us language for the beings and changes of the inward creation.”
—Ralph Waldo Emerson (1803–1882)
“A book should contain pure discoveries, glimpses of terra firma, though by shipwrecked mariners, and not the art of navigation by those who have never been out of sight of land. They must not yield wheat and potatoes, but must themselves be the unconstrained and natural harvest of their author’s lives.”
—Henry David Thoreau (1817–1862)
“The history of philosophy is to a great extent that of a certain clash of human temperaments.”
—William James (1842–1910)
