Hunting Districts 315 and 580)
CRAZY MOUNTAINS EMU (Hunting Districts 315 and 580) Description: This 1,708-square-mile EMU includes the Crazy Mountain Range and adjacent foothill and prairie habitats in south central Montana. The area is a mixture of private (78%) and public (22%) lands, including portions of both the Gallatin and Lewis and Clark national forests (16%), state school trust lands (DNRC – 5%), and USDI Bureau of Land Management (BLM – 0.2%). Land ownership patterns within the boundary of the national forests are characterized by checkerboard ownership. The EMU contains two roadless areas encompassing 149,467 acres of public and private lands that offer wilderness-type recreation. However, much of this roadless area is not elk habitat. This EMU contains over 590,000 acres of occupied elk habitat (54% of EMU). National forest lands provide a large portion of spring, summer and fall elk habitat, but private lands in mountain foothill and sagebrush-grassland habitats provide over 80% of elk winter range during normal winters and virtually all of the available winter range during severe winters. Public Access: Access by road to elk habitat is limited in most of HD 580 where the checkerboard pattern of land ownership complicates management of access. With few exceptions, public access to elk habitat on the north and east slopes of the Crazies is controlled entirely by private landowners. There are only 3 points in HD 580 where the public may legally access national forest lands – the Big Timber Canyon road in the southeast corner, the Cottonwood Creek/Forest Lake road on the north end and Sixteenmile Creek in the northwest corner of the hunting district. -
Stratigraphy and Depositional Environment of the Upper Mississippian Big Snowy Group in the Bridger Range, Southwest Montana By
Stratigraphy and depositional environment of the Upper Mississippian Big Snowy Group in the Bridger Range, southwest Montana by Gary Eich Guthrie A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Earth Science Montana State University © Copyright by Gary Eich Guthrie (1984) Abstract: The Big Snowy Group is restricted to a trough which extends from southwest Montana into the Williston basin. Thickness variation of the group on the southern margin of the trough reflects movement of structural elements along an ancient structural weakness located in the central Bridget Range. Field and petrographic data are integrated to determine the depositional environment and stratigraphy of the group and to document the tectonic influence on sedimentation along this zone. The group is divided into the Kibbey Formation, with two informal members, and the Lombard facies of the Heath Formation. The lower Kibbey is supratidal algal laminated dolostone with dessication features and evaporite solution breccias were deposited at the leading edge of the transgressing Big Snowy sea. Siliciclastic intertidal channels on the sabkha are restricted to the central range where subsidence was greatest. The upper Kibbey and Lombard facies provide further evidence of a trough in the central Bridgers. The upper Kibbey is a regressive shoreface deposit composed of fine grained sandstone at the northern and southern ends of the range. Mudstone and siltstone dominate in the center of the range where deeper water and lower energy conditions prevailed. Ultimately, the Kibbey shoreface transgressed out of the area and the Lombard facies was deposited in a partially restricted shelf lagoon. -

Synorogenic Basin Deposits and Associated Laramide Uplifts in the Montana Part of the Cordilleran Foreland Basin System
SYNOROGENIC BASIN DEPOSITS AND ASSOCIATED LARAMIDE UPLIFTS IN THE MONTANA PART OF THE CORDILLERAN FORELAND BASIN SYSTEM Susan M. Vuke Montana Bureau of Mines and Geology, Butte, Montana ABSTRACT The North American Cordilleran Foreland Basin System extended from the eastern edge of the Cordilleran Sevier fold-thrust belt in western Montana across central and eastern Montana from Jurassic into early Paleo- gene time. In the central and southern Montana part of the system, isolated Laramide basement-cored uplifts and sedimentary basin pairs characterize the main Laramide Province. The thrust/reverse fault-propagated arches and basins of the province developed primarily during Late Cretaceous through earliest Eocene time, although regionally, initiation of uplift may have occurred during Early to middle Cretaceous time in southwest- ern Montana. Associated prominent WNW–ESE- and NE–SW-striking linear features refl ect Laramide reactiva- tion of basement faults that now extend to the surface, or are entirely in the subsurface. They occur throughout the main Laramide Province and are likely genetically related to development of the uplift-basin pairs. The asymmetric Laramide Bighorn and Powder River Basins developed in association with uplift along basin-bounding thrust/reverse faults of the Beartooth and Bighorn basement-cored arches, respectively. Thrust loading associated with uplift along the faults propagated asymmetric synclinal basin folds that accommodated the greatest thicknesses of synorogenic deposits adjacent to the range-bounding faults. In Montana, synorogenic deposits of the Bighorn Basin primarily include the Paleocene Fort Union Formation, and those of the Powder River Basin primarily include the Paleocene Fort Union and Eocene Wasatch Formations. -
