The Siskiyou Loop: Discovery Tour The Siskiyou Loop: Discovery Tour Would you like to take a trip of discovery into the mountains near Medford and Ashland? The Siskiyou Loop is an 85-mile long drive that will take you from the Medford-Ashland area – via Jacksonville and the equally historic Applegate Valley – up along the scenic crest of the rugged Siskiyou Mountains, and return you to Interstate Five and the Rogue River Valley. Along this self-guided “discovery tour” through parts of two National Forests you will: z view managed forestlands; z observe interesting geology, flora, and fauna; z visit historic sites; z and see some beautiful, near-pristine backcountry.

  • Little Applegate Hydrology Report
    Little Applegate Watershed Hydrology Report Michael Zan * Hydrologist April 1995 Little Applegate Watershed Analysis Hydrology Report SECTION 1 LITTLE APPLEGATE RIVER HYDROLOGY Mean Monthly Flows: Except for some data collected from May through October 1913, and from June through October 1994. there is no known flow data for the Little Applegate River or its tributaries. With this in mind it was necessary to construct a hydrograph displaying mean monthly flows by utilizing records from nearby stations that have been published in USGS Surface Water Records and Open-File Reports. In constructing a hydrograph, a short discussion of low flows is first in order. Since low streamflows have been identified as a key question pertaining to the larger issues of water quantity/quality and fish populations, the greatest need is to gain a reasonable estimate of seasonal low flows to help quantify the impacts of water withdrawals on instream beneficial uses. With this in mind, extreme caution must be used when extrapolating data from gaged to ungaged watersheds. This is particularly important in determining low-flow characteristics (Riggs 1972, Gallino 1994 personal communications). The principle terrestrial influence on low flow is geology and the primary meteorological influence is precipitation. Neither have been adequately used to describe effects on low flow using an index so that estimation of low flow characteristics of sites without discharge measurements has met with limited success. Exceptions are on streams in a region with homogeneous geology, topography, and climate, in which it should be possible to define a range of flow per square mile for a given recurrence interval.

  • A Bibliography of Klamath Mountains Geology, California and Oregon
    U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY A bibliography of Klamath Mountains geology, California and Oregon, listing authors from Aalto to Zucca for the years 1849 to mid-1995 Compiled by William P. Irwin Menlo Park, California Open-File Report 95-558 1995 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards (or with the North American Stratigraphic Code). Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. PREFACE This bibliography of Klamath Mountains geology was begun, although not in a systematic or comprehensive way, when, in 1953, I was assigned the task of preparing a report on the geology and mineral resources of the drainage basins of the Trinity, Klamath, and Eel Rivers in northwestern California. During the following 40 or more years, I maintained an active interest in the Klamath Mountains region and continued to collect bibliographic references to the various reports and maps of Klamath geology that came to my attention. When I retired in 1989 and became a Geologist Emeritus with the Geological Survey, I had a large amount of bibliographic material in my files. Believing that a comprehensive bibliography of a region is a valuable research tool, I have expended substantial effort to make this bibliography of the Klamath Mountains as complete as is reasonably feasible. My aim was to include all published reports and maps that pertain primarily to the Klamath Mountains, as well as all pertinent doctoral and master's theses.

Like everyone, 2020 has been a tough year for us. But I hope this issue illustrates that this year was a challenge we were up for. We had to make big changes, including a hiring freeze on interns and seasonals. My staff, board, our volun- teers, and I all had to flex into what roles needed to be filled, and far-ahead planning became almost impossi- ble. But we were able to wrap up technical frontcountry projects in the spring, and finished work on the Briggs Creek Bridge and a long retaining wall on the multi-use Taylor Creek Trail. Then my staff planned for a smaller intern program that was stronger beyond measure. We put practices in place to keep everyone safe, and got through the year intact and in good health. This year we had a greater impact on the lives of the young people who serve on our Wilderness Conserva- tion Corps. They completed media projects and gained technical skills. Everyone pushed themselves and we took the first real steps in realizing greater diversity throughout our organization. And despite protocols in place to slow the spread of Covid-19, we actually grew our volunteer program.

    Field Trip Guide to the Upper Cretaceous Hornbrook Formation and Cenozoic Rocks of southern Oregon and northern California Students in SOU’s field geology course examining sandstones of the Rocky Gulch Member of the Hornbrook Formation near Hilt, California. Field Trip Leader: Bill Elliott Department of Geology, Southern Oregon University Saturday, September 8, 2007 Introduction The Klamath Mountains are an elongated north-trending geological province that occupies approximately 19,000 km2 in southwestern Oregon and northern California. The Klamath Mountains are made-up of numerous terranes that accreted during the Antler (Devonian), Sonoman (Permian to Late Triassic), and Nevadan (Jurassic to Early Cretaceous) orogenies (Mortimer, 1984). These terranes have been grouped into four metamorphic belts, from oldest (east) to youngest (west): Eastern Klamath Belt; Central Metamorphic; Western Paleozoic and Triassic; and Western Jurassic (Irwin, 1966; Irwin, 1994). In the Late Jurassic to Early Cretaceous, numerous magma bodies intruded the Klamath Mountains, including the Jurassic Mt. Ashland pluton and Early Cretaceous Grants Pass pluton (Hotz 1971; Gribble et al., 1990). During the Late Jurassic to Early Cretaceous, a subduction zone complex and forearc basin developed along the western margin of North America while folding and thrusting of Paleozoic and lower Mesozoic rocks associated with the Sevier orogeny triggered the formation of the Cordilleran foreland basin in the interior of North America (Figs. 1 and 2). The Hornbrook Formation (Upper Cretaceous) consists of a sequence of dominantly marine clastic sedimentary rocks about 1,200 meters thick exposed along the northeastern margin of the Klamath Mountains in southwestern Oregon to northern California (Fig.
