Aggregates – Sand & Gravel Potential

This data layer is the Sand and Gravel Potential component of the Minnesota Aggregate Resource Mapping Program (ARMP) dataset. It was developed by the Minnesota Department of Natural Resources. The Sand and Gravel Potential layer includes information about the geology, geological characteristics, and sand and gravel potential for select counties across the state. Aggregates are necessary for the construction of roads and buildings and are costly to transport. The goals of the ARMP include providing a better understanding and responsible use of the state's aggregate resources.
