Geologic Mapping in Saint Croix National Scenic Riverway

A geologic scoping meeting at Saint Croix National Scenic Riverway (SACN) identified significant gaps in the existing geologic map coverage in and adjacent to the park boundaries. Some areas were mapped at too coarse a scale to have any resource management utility, some areas had bedrock but no surficial mapping, some had surficial but no bedrock, and some had never been mapped at all. This project will first fill in all missing surficial geologic mapping, and, if funding is available, then fill in the bedrock mapping. This sequence was selected at the request of the park who finds surficial maps to have the most utility for resource management.
