The grand landscapes and river systems of Mount Rainier National Park (MORA) are influenced by its glaciovolcanic geology and the temperate climate of the Pacific Northwest. Mapping geomorphic changes is a crucial step to understanding, interacting with, and preserving the pristine environments of the Park. Geologic hazards and large-scale hydrologic events are common within park boundaries, putting infrastructure and cultural and historical sites at risk of permanent damage. In this study, I present a protocol for mapping geomorphic features remotely and in the field, and I test the protocol along an at-risk road segment along the Nisqually River. With ArcGIS Pro, I defined site boundaries with a watershed delineation, designated key geomorphic features custom to the unique environment of the Park, and assigned key attribute domains to further describe each mapped feature. Then, I mapped landform features using LiDAR and aerial imagery in Pro and used ArcGIS Online and Field Maps for in-field mapping with a mobile tablet and a backpack-mounted GNSS receiver. After extensive testing, the protocol is in its preliminary phase and ready to be applied to other park field sites for further testing and repeat mapping projects. The resulting inventory suggests that the protocol is suitable for the remote and rugged characteristics of the Park when paired with recent LiDAR data and favorable GNSS conditions. The standardized methods and taxonomy proposed in the protocol allow for recording landform changes and initial site characterization that can be used to identify locations for hazard mitigation. The protocol is repeatable, providing a standardized format useful for comparison between different locations and timescales. While the protocol is designed for the features found near Mount Rainier, it can be readily modified for other fluvial and hillslope environments. In its final form, this geomorphic mapping protocol will equip MORA geologists and resource managers with a standard approach to documenting MORA's most geologically dynamic and at-risk infrastructure and resources.
