CSD geologists conduct field surveys and employ test-hole drilling to construct surficial geologic maps of the exposed land surface throughout Nebraska. Data is collected and interpreted to provide quadrangle (quad) maps that identify geologic units and physical characteristics of subsurface material through test-hole drilling while also illustrating natural topographical features. Surficial geologic maps are a preliminary tool in site evaluation and are used to assess land use; water, mineral and construction material resources; geomorphological changes; and geohazards.
The Conservation and Survey Division, through a cooperative agreement with the USGS National Cooperative Geologic Mapping Program (NCGMP), produces surficial geologic maps of Nebraska for the STATEMAP Program. CSD has been awarded matching grants through the program since 1994.
