 "description": "<div><br /><\/div><div><span style='color:rgb(0, 0, 32); font-family:calibri; font-size:16px;'>This spatial dataset of crushed stone resource potential is based on a compilation of GIS aggregate resources (sand and gravel, crushed stone) reconnaissance scale data spanning twenty county projects completed over a number of years (1987-present) by the DNR's Aggregate Resource Mapping Program (ARMP). The attribute data available varies as a result of the varied years of completion and changes in databases structure and verbiage over time. The past project GIS data has been loaded into the current file geodatabase used by the Aggregate Resource Mapping Program. Therefore the data from the most recent completed counties (Aitkin, Stearns, Kanabec, Olmsted) have the most complete attribute table, while the earlier mapped counties (Sherburne, Wright, Isanti) have limited attribute data. Unlike sand and gravel potential data, crushed stone potential is not found in every county or project area due to it being not good quality bedrock or too far below the surface (greater than 50 feet) to extract economically today. Digital crushed stone resource potential was first delineated for Blue Earth County Project completed in 1999. Since then 11 other counties have had crushed stone resource potential mapped. The attribute data varies by county since database design has changed since 1999.<\/span><br /><br /><span style='color:rgb(0, 0, 32); font-family:calibri; font-size:16px;'>Generally speaking the dataset consists of information about the geology, geological characteristics, and aggregate potential of crushed-stone potential units. Four attribute fields relate to crushed stone characteristics, including overburden thickness, quality, probability, and bedrock geological unit. These characteristics were used to calculate the aggregate potential of the map unit for crushed stone.<\/span><br /><\/div>",
