This dependence on groundwater raises important questions regarding the Madison and Minnelusa aquifers in and near the Black Hills of South Dakota, including groundwater availability, the effects of water use or drought, mixing of regional flow and local recharge, and the effects of capture zones of springs and wells on the groundwater-flow system. These questions are best addressed with a three-dimensional numerical groundwater-flow model that

  • 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.

  • Jurassic Onset of Foreland Basin Deposition in Northwestern Montana, USA: Implications for Along-Strike Synchroneity of Cordilleran Orogenic Activity
    Jurassic onset of foreland basin deposition in northwestern Montana, USA: Implications for along-strike synchroneity of Cordilleran orogenic activity F. Fuentes*, P.G. DeCelles, G.E. Gehrels Department of Geosciences, University of Arizona, Tucson, Arizona 85721, USA ABSTRACT Stratigraphic, provenance, and subsidence analyses suggest that by the Middle to Late Jurassic a foreland basin system was active in northwestern Montana (United States). U-Pb ages of detrital zircons and detrital modes of sandstones indicate provenance from accreted terranes and deformed miogeoclinal rocks to the west. Subsidence commenced ca. 170 Ma and followed a sigmoidal pattern characteristic of foreland basin systems. Thin Jurassic deposits of the Ellis Group and Morrison Formation accumulated in a backbulge depozone. A regional unconformity and/or paleosol zone separates the Morrison from Early Cretaceous foredeep deposits of the Kootenai Formation. The model presented here is consistent with regional deformation events registered in hinterland regions, and challenges previous interpretations of a strongly diachronous onset of Cordilleran foreland basin deposition from northwestern Montana to southern Canada.
