Saint Croix National Scenic Riverway: Geologic and Soil Resources Inventory Summary
Harrington M. 2026. Saint Croix National Scenic Riverway: Geologic and Soil Resources Inventory Summary. National Park Service. Lakewood, CO
This document summarizes the status of National Park Service (NPS) Geologic Resources Inventory (GRI) and Soil Resources Inventory (SRI) deliverables for Saint Croix National Scenic Riverway. It also provides information on current geology and soils resource management concerns with a focus on identified inventory needs related to geologic heritage, geohazards, and related soil features and processes. This document is intended to assist park staff with prioritizing technical assistance or new inventory and assessment funding requests in the near term (roughly 1 –5 years). GRI hosted a baseline scoping meeting for Saint Croix National Scenic Riverway in 2010. Baseline surficial geologic maps were delivered to the park in 2022 with updated surficial geologic maps delivered in 2026. SRI delivered a legacy soil database and map to the park in 2007. Geologic heritage resources of particular interest include glacial features, Indigenous connections, the legacy of the fur trade, logging industry, and mining, paleontological resources, caves, and a rich recreational history. Inventory needs include updated bedrock mapping and monitoring at-risk paleontology sites. Geohazards include erosion, mass wasting, flooding, radon, and abandoned mineral lands. Inventory needs include a comprehensive inventory of historic mining sites and monitoring known slumping/mass wasting sites. Additional guidance for park staff regarding proposal processes and timeframes for the new Inventories and Assessment (I&A) program is available on the GSRI and I&A SharePoint sites.
