Landforms/Geology/Floodplain Data Description

Topographic maps (1:24,000)

Restoration Planning  These maps may be useful for larger planning efforts, but the scale will be too coarse for local projects.  Features shown on these maps may not reflect recent changes in land use.

Data Description  The TopoFinder from NRIS allows the user to view and zoom in on 1:24000 USGS topographic maps on-line.  NRIS also provides links on this page to download these images in TIFF or MrSID format for use with image viewing or GIS software on your local computer.  Downloadable maps are available at scales of 1:24,000, 1:100,000 and 1:250,000.  The TopoFinder allows you to download a single
1:100,000 OR 1:24,000 scale topographic map OR a digital orthophoto quadrangle that covers the center of the map you are viewing.  Note: orthophotos are not shown until you zoom in so that the scene viewed is less than 3 miles across. Once you see a photo, you can download it. You will download the whole photo even if you zoom in on a little part of it.  (see description of orthophotoquads below)

Digital orthophotos (aerial photos)

Restoration Planning  These photos may be useful for larger planning efforts, but the scale will be too coarse for local projects.  Features shown on the photos may not reflect recent changes in land use.

Data Description  The TopoFinder from NRIS allows the user to view and zoom in on USGS orthophotos (aerial photos) by toggling from the topographic map view.  The date of each photo is shown below the image.  Photo coverage in the Upper Clark Fork Basin ranges from the late 1980's -1995.  From this page, one may also download the image to a local system.  The TopoFinder allows you to download a single
1:100,000 OR 1:24,000 scale topographic map OR a digital orthophoto quadrangle that covers the center of the map you are viewing.  Note: orthophotos are not shown until you zoom in so that the scene viewed is less than 3 miles across. Once you see a photo, you can download it. You will download the whole photo even if you zoom in on a little part of it.  

All of the Upper Clark Fork River basin is currently covered; a status map of the NRIS data inventory is
available at:  http://nris.state.mt.us/nsdi/doq.asp

Digital elevation models

Restoration Planning  Digital elevation maps models are useful for GIS analysis. They comprise data from which other maps can be developed such as slope or aspect mapping. 

Data Description  Data are available by download only on this NRIS page.  Information comes from the National Elevation Dataset.  Each file downloaded from this page consists of sixteen 7.5-minute DEM quadrangles that have been joined together. Individual maps may be available by contacting NRIS.  Data quality in the Upper Clark Fork Basin is variable from place to place, ranging from good to poor.

Geologic map of the Butte 1:250,000 quadrangle

Restoration Planning  The scale of this map is too coarse for small targeted areas, but could be useful as an overall indicator of major geologic units and structures in the Upper Clark Fork Basin.

Data Description  This geologic map showing lithology and structure is available via FTP download from the MBMG.  It is also available in hard copy from the MBMG in Butte as Open File Report 363.  The map was produced in 1998 by R.S. Lewis.

Printed References - Geology

The Montana Bureau of Mines and Geology publications database includes all Bureau publications as well as USGS publications related to Montana geology and hydrogeology.  (Currently, not all USGS material is included.)  The database is searchable by author, keyword, county, or publication type.  References include geological, geophysical and geochemical reports and maps.  Links on the displayed references describe where the reference can be purchased, and purchase price.  Most publications are also available in the Montana Tech library.  Contact information: pubsales@mtech.edu or 406/496-4174

Other printed references (USGS and UM theses): (Not available on-line - UM theses can be borrowed from the Mansfield Library - the USGS report is also available here, and at other regional libraries) 

Cremer, E. A., 1966, Gravity determination of basement configuration, southern Deer Lodge Valley, Montana.  M.S. Thesis, University of Montana.  Thesis provides a map of depth to bedrock and thickness of alluvium in the Deer Lodge Valley. Potentially useful for developing groundwater flow models in the Deer Lodge Valley

Konizeski, R. L., R.G. McMurtrey, and A Brietkrietz, 1968, Geology and groundwater resources of the Deer Lodge Valley, Montana.  USGS Water- Supply Paper 1862, 55p.  The report summarizes the geology of the valley including description and extent of geologic units and aquifers.  Useful background information for identifying aquifers and flow systems in this area.

McLeod, P.J., 1987, The depositional history of the Deer Lodge Basin, Western Montana.  M.S. Thesis, University of Montana.  This investigation includes lithologic description of deep boreholes in this region. Useful background information for identifying deep aquifers and potentially useful for developing groundwater flow models.
