Missouri National Recreational River: Geologic and Soil Resources Inventory Summary
Henderson T. 2025. Missouri National Recreational River: Geologic and Soil Resources Inventory Summary. National Park Service
This document summarizes the status of National Park Service (NPS) Geologic Resources Inventory (GRI) and Soil Resources Inventory (SRI) deliverables for Missouri National Recreational River. It also provides information on current geology and soil resources 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). The GRI hosted a baseline scoping meeting for Missouri National Recreational River in 2008. Baseline bedrock and surficial geologic maps were delivered to the park in 2021 and updated in 2023. SRI delivered a legacy soil database and map to the park in 2010. The most up-to-date soil data for the recreational river is available through Web Soil Survey. Missouri National Recreational River’s geologic heritage is ingrained in its paleontology, Indigenous connections, stratotypes, ecological diversity, and scenic values, as well as its connections to the Lewis & Clark Expedition and early steamboat history. Geologic hazards identified in the park include cave and karst development, climate change, disturbed lands (e.g., dams, riverbank stabilization, land use, energy infrastructure), flooding, mass wasting (e.g., slumps, rockfalls, or rockslides), radon, seismicity, swelling clays, and toxicological soils. The geologic and soil resources inventory needs for the park include various data and/or GIS needs related to the inventory and monitoring of cultural resources, geohazards, geomorphology, hydrological resources, and fossils, in addition to natural resource management needs.
