On the 15th day of April, 1853, at Independence, Missouri an immigrant train was leaving for great Oregon Territory, as they supposed, but which had, in the interim of their coining, become the Ter- ritory of Washington. The founders of this train, with their families, household goods, supplies and other necessary equip- ments, loaded into a dead-" wagon, drawn by oxen, though a few had horses, started on their long, laborious journey- to an unknown country-in number less than one hundred-people, all told. They were six months on the way, but increased their numbers enroute to one hundred and seventy- five people, by smaller companies joining them. On leaving Independence, the party realized the necessity of having a Captain, and to that end Mr. James Biles was chosen, with William R. Downey, Bartolomew Baker, Charles Biles, and Nelson Sargent as Assistants.

  • Puget Sound Salmon Habitat Assessment: Landscape Level Subwatershed Prioritization
    CONSERVATION PRIORITIES: AN ASSESSMENT OF FRESHWATER HABITAT FOR PUGET SOUND SALMON PREFACE This report entitled Conservation Priorities: An assessment of freshwater habitat for Puget Sound Salmon was prepared at the request of the Trust for Public Land (TPL) to provide a regional snapshot of Puget Sound’s most pristine, intact freshwater salmon habitat. TPL is a leading land conservation organization whose mission includes conserving land for people which often means protecting habitat critical to the health of salmon and other species. We believe the assessment can complement and enhance the work of many organizations that are striving to recover our Puget Sound salmon runs. The assessment is a synthesis of existing information and expert opinion. The report describes or attempts to draw from what is known, published and described by experts within agencies, tribes and watershed groups having direct knowledge of these ecosystems and populations. The assessment provides a priority listing and map of the most intact freshwater habitats for salmon in the Puget Sound. The prioritized list of habitats, together with the summarized information and compiled sources, can be used to help guide cost- effective conservation decision making in the near term for the benefit of salmon and encompasses the whole Puget Sound basin. Dr. Chris Frissell, of the Flathead Lake Biological Station at the University of Montana; Peter Morrison, Pacific Biodiversity Institute; Jim Kramer, natural resource consultant; and Marie Mentor, a consultant and former TPL Washington State Director, were retained to produce the assessment. This effort would not have been possible without the significant support provided by The Brainerd Foundation, the Kongsgaard-Goldman Foundation, King County, the Bullitt Foundation, and in-kind contributions from Pacific Biodiversity Institute and TPL.

    NACHES PASS Far up in the Cascade Range, at an elevation of 4,988 feet, lies historic Naches Pass. From Pyramid Peak, on the north side, may be seen Mount Rainier to the southwest, rising in all its gran­ deur above the surrounding country, while off toward the southeast the canyon of the Naches River extends on to the great Yakima Val­ ley. Four counties of the state of Washington meet at the Pass­ Kittitas on the northeast, Yakima on the southeast, Pierce on the southwest, and King on the northwest. Mountain ranges are barriers to the advancement of railroads, and it is only by boring tunnels or laying tracks over the pass, if Providence has been thoughtful enough to provide them at not too high an altitude, that their routes may be extended from one side to the other. Through the Cascade Range, in this state, are twelve main passes, the lowest of which, Snoqualmie, WIth an elevation of 3,004 feet, was chosen by the Milwaukee Road; while the next lowest, Stevens, with an elevation of 4061 feet, was the choice of the Great Northern. Instead of having used one of the remaining passes, the Northern Pacific Railroad made its way from one side of the Range to the other by means of the Stampede Tunnel, about eleven miles from Easton. Naches Pass is the fifth lowest, while Chinook Pass, selected for the highway across the Cascades, ranks ninth, with an elevation of 5440 feet. H the Cascade Range was such a hindrance to the on-coming railroads, what must it have been to the emigrants! No wonder that those coming from the east to settle in the Puget Sound country em­ barked on long sea voyages around the Horn, or came across the plains by wagon trains until they reached the Columbia, then went by boat down the river and up one of its tributaries, then perhaps overland for some distance, and possibly a trip on some portion of the Sound to their destinations.
