The Future of Stream Access in Montana
2017 The Best in the West: Stream Access in Montana Public Land/Water Access Association High Water by Mary J. Maxam By Brent Zundel For the Public Land/Water Access Association April 2017 Keeping the public on public lands and waters Overview Montana’s Stream Access Law is widely considered “the best in the west,” arguably the strongest law in the nation in terms of ensuring public access. In short, the public can access any river or stream capable of being used for recreation between the high-water marks, regardless of the navigability of the river or the ownership of the streambed and adjacent property, as long as the user avoids trespass in order to reach the stream. This document provides a history of stream access in Montana, beginning with the original conflicts on the Dearborn and Beaverhead Rivers and continuing to the recently decided battles over access at bridges and the most recent challenge to the Stream Access Law. Early conflicts in the late 1970s and early 1980s led to the groundbreaking Curran The Yellowstone River flows through Paradise Valley, south of Livingston, and Hildreth cases in the Montana. Photo courtesy Brent Zundel Montana Supreme Court. These cases laid the foundation for the groundbreaking 1985 Stream Access Law, which codifies the strong public access rights enjoyed by all Montanans today. Immediately upon passage of the law, it was challenged in district courts, the state supreme court, and even appealed to the federal level. It has withstood all challenges. In the past decade, those fighting against public access have shifted to focus on stream access at bridges, with much of the controversy centering on the iconic Ruby River. -

Research Natural Areas of the Northern Region: Status & Needs Assessment
NATURAL AREAS ASSESSMENT, OCTOBER 1996 1 Research Natural Areas of the Northern Region: Status & Needs Assessment October 1996 Steve W. Chadde Shannon F. Kimball Angela G. Evenden INTRODUCTION A MAJOR OBJECTIVE of the Forest Service Research Natural Area (RNA) program is to maintain a representative array of all significant natural ecosystems as baseline areas for research and monitoring (Forest Service Manual 4063, USDA Forest Service 1991). The National Forest Management Act of 1976 directs the agency to establish research natural areas typifying important forest, shrubland, grassland, alpine, and aquatic ecosystems. In addition to their value as reference areas for research and monitoring, RNAs help maintain biological diversity and healthy ecosystems on national forests by conserving assemblages of common and rare species, undisturbed plant communities, aquatic systems, and unique landscape features such as wetlands and ancient cedar groves. To achieve these objectives, the 1983 Northern Regional Guide (USDA Forest Service 1983) included a matrix of habitat types, community types, and aquatic features targeted for inclusion in the Northern Region research natural area system. Within each of four analysis areas (northern Idaho, western Montana, central and eastern Montana, North and South Dakota), filled target cells were identified and unfilled target assignments were made to each National Forest. Since 1983, much progress has been made toward a comprehensive research natural area system in the Northern Region. Many RNAs have been formally established (from 13 in 1983 to 67 in 1996) and 50 others are proposed, primarily through the forest planning process (Table 1, Figures 1-2). NEED FOR PROGRAM UPDATE Our knowledge of the Region’s ecological features has changed since 1983. -

Stratigraphy and Structure of Part of the Southern Madison Range, Madison and Gallatin Counties, Montana
AN ABSTRACT OF THE THESIS OF Robert Rowland Rose' for the M.S. in Geology (Name) (Degree) (Major) Date thesis is presented Title STRATIGRAPHY AND STRUCTURE OF PART OF THE SOUTHERN MADISON RANGE, MADISON AND GALLATIN COUNTIES. MONTANA Abstract approved (Major professor The thesis area consists of 42 square miles located in Madison and Gallatin counties, Montana, in the south- ern part of the Madison Range. The strata exposed in the area range in age from Precambrian to Quaternary and have an aggregate thickness of more than 7,600 feet. The Paleozoic rocks, about 3,900 feet thick, are mainly carbonates but include sandstones, shales, and cherts of marine origin. Ordovician and Silurian forma- tions are absent. The Mesozoic rocks consist mainly of sandstones, shales, calcareous claystones, and argillaceous limestones of marine and continental origin. All Mesozoic periods are represented in this 3700 foot thick sequence of sedimentary rocks. The Cenozoic rocks and sediments include welded tuff, glacial deposits, and alluvium. Quaternary landslides cover about one -quarter of the thesis area. The structures are Late Cretaceous to Early Tertiary (Laramide) and Late Cenozoic in age. The Laramide struc- tures are northwest- trending, asymmetrical (steeper to the northeast) folds and high angle reverse faults. The Late Cenozoic structures are normal faults that displace Upper Cretaceous strata.
