Image: Missouri karst feature distribution v1

Description: This map depicts the distribution of these karst-related features in the state of Missouri: Relative cave density per USGS 7.5" quadrangle is depicted by shades of red, deeper red signifying a larger number of caves in the quadrangle. Stretches of losing streams streams are shown in yellow. Known springs are shown as filled blue circles. (Note the data does not contain any indication of freshwater vs. mineral or saline springs.) Layers are rendered from these datasets: Originator: Missouri Department of Natural Resources (MoDNR), Division of Geology and Land Survey (DGLS), Geological Survey Program (GSP) Publication_Date: 20060609 Publication_Time: Unknown Title: Cave Density Originator: Missouri Department of Natural Resources (MoDNR), Division of Geology and Land Survey (DGLS), Geological Survey Program (GSP) Publication_Date: 20060712 Title: SPRINGS Originator: Missouri Department of Natural Resources (MoDNR), Division of Geology and Land Survey (DGLS) Originator: Geological Survey Program (GSP), Environmental Geology Section (EGS) Publication_Date: 20070326 Title: LOSING_STREAM This map is rendered with an Albers equal area projection that is described in "proj" format as: +proj=aea +lon_0=-92.00 +lat_1=37.5 +lat_2=39.667 +x_0=0 +y_0=0 +ellps=clrk66 +datum=WGS84 +units=m +no_defs This SVG map was prepared directly from the original shapefile data with the free "shptosvg.pl" utility written in Perl and available at http://www.github.com/kbh3rd/shptosvg. That utility incorporates other free software modules distributed through http://www.cpan.org/. The final touches were performed with Inkscape, another free software product (http://www.inkscape.org/).
