Item Bulletin No. 18. The Foundry Sands of Minnesota(Minnesota Geological Survey, 1923) Knapp, G.N.This paper, on the sands of Minnesota, is a report of an investigation begun in 1918, at a time when there was a great demand for information about local molding sands. as a result of the traffic situation that made it difficult or impossible to obtain sands from sources that had previously supplied them. The inquiry, which was in charge of Mr. G. N. Knapp, showed that Minnesota contains an abundance of sands for founding nearly all products. equal to, or better than, the sands that had been imported. Part of the information embodied in the report was placed at the disposal of the metal founders as soon as it became available, either verbally or by means of mimeographed sheets. The field work showed also that molding materials are more widely spread over the state than was supposed. and a fairly comprehensive reconnaissance was made of a considerable part of Minnesota. Materials gathered from widely separated sources were tested in the laboratory and some were tested by founders in their plants. Minnesota contains an abundance of foundry sands and all materials commonly used for making molds in foundries of iron, steel, brass, and aluminum, except possibly a highly plastic refractory clay. An economic bulletin such as this is chiefly utilitarian. It should show the nature of materials used, the tests made to ascertain the value of the materials, and the distribution of the materials in the state. These subjects are taken up separately in this bulletin and the geologic and geographic distribution are discussed in some detail. The report does not contain a geologic map. To have included such a map would have resulted in duplication.Item C-43, Geologic Atlas of Cass County, Minnesota(Minnesota Geological Survey, 2018) Lusardi, Barbara, A; Pettus, Margeurite, C; Chandler, Val, W; Radakovich, Amy, L; Nguyen, Maurice, K; Staley, Amie, E; Hamilton, Jacqueline, DA County Geologic Atlas project is a study of a county's geology, and its mineral and ground-water resources. The information collected during the project is used to develop maps, data-base files, and reports. This same information is also produced as digital files for use with computers. The map information is formatted as geographic information system (GIS) files with associated data bases. The maps and reports are also reproduced as portable document files (PDFs) that can be opened on virtually any computer using the free Acrobat Reader from Adobe.com. Due to errors identified during work on the Part B portion of the atlas, new strat lines and sand/till rasters have been added to this site to address the issues (Revisions to sand model data 2022).Item C-46, Geologic Atlas of Kandiyohi County, Minnesota(Minnesota Geological Survey, 2019) Hamilton, Jacqueline D; Bauer, Emily J; Chandler, V.W.; Steenberg, Julia R; Staley, Amie EA County Geologic Atlas project is a study of a county's geology, and its mineral and ground-water resources. The information collected during the project is used to develop maps, data-base files, and reports. This same information is also produced as digital files for use with computers. The map information is formatted as geographic information system (GIS) files with associated data bases. The maps and reports are also reproduced as portable document files (PDFs) that can be opened on virtually any computer using the free Acrobat Reader from Adobe.com. Due to errors found when working with Part B, hydrogeology, revised sand/till rasters have been added to this site in 2022 (Revisions to sand model data 2022).Item C-51, Geologic Atlas of St. Louis County, Minnesota(Minnesota Geological Survey, 2022) Bauer, Emily J; Jirsa, Mark A; Block, Amy R; Boerboom, Terrence J; Chandler, V.W.; Peterson, Dean M; Wagner, Kaleb G; McDonald, Jennifer M; Dengler, Elizabeth L; Meyer, Gary N; Hamilton, Jacqueline DA County Geologic Atlas project is a study of a county's geology, and its mineral and ground-water resources.

Affected communities face issues relating to land tenure and governance, and often experience violations of their procedural rights to public participation, access to information, and access to justice. This report analyzes the major human rights impacts of sand extraction in the Upper Midwestern United States, Kenya, and India, incorporating the perspectives of various stakeholders and evaluating the relevant legal and regulatory structures and practices for each case. Employing a qualitative research approach informed by literature review, stakeholder and expert interviews, and media analysis, we describe the human rights situation in each location and identify major trends characterizing the issue across different human, political, and physical geographies. We conclude by offering recommendations for States, businesses, and civil society organizations to respect, protect, and fulfill the human rights threatened by sand extraction.
