From the site: “The Geologic Atlas of the United States is a set of 227 folios published by the U.S. Geological Survey between 1894 and 1945. Each folio includes both topographic and geologic maps for each quad represented in that folio, as well as description of the basic and economic geology of the area. The Geologic Atlas collection is maintained by the Map & GIS Library. The repository interface with integrated Yahoo! Maps was developed by the Digital Initiatives -- Research & Technology group within the TAMU Libraries using the Manakin interface framework on top of the DSpace digital repository software. Additional files of each map are available for download for use in GIS or Google Earth. A tutorial is provided which describes how to download theses files.”

The township boundary is used by Magistrates in York County SC to determine the jurisdiction of civil cases. Civil cases should (typically) be filed in the jurisdiction where the defendant/ plaintiff resides due to servicing (to prevent someone from driving across the county to be assisted with a court matter). Plaintiffs/ defendants have a right to have their case heard in their own township by a potential jury of their own peers. (Of note, Magistrate lines don’t match up with township lines. Magistrate lines may not be useful if the judges have countywide jurisdiction.) Square Miles area was added as a calculated attribute (Arcade, AreaGeodetic) Feb 2022 by request.As of 9/2023 Magistrate lines are not used. Instead, township lines are used to determine areas represented by Judge. Some judges cover over more than one township and city in parenthesis is the town where the office is located:

York County is divided into five geographical areas called townships. There is one Judge for each of the townships. The Townships are: (office location in parenthesis): Bethel-Kings Mountain (Clover), Broad River-Bullocks Creek (Hickory Grove), Catawba-Ebenezer (Rock Hill), Fort Mill (Fort Mill), York-Bethesda (York).
