This repository contains CSV files summarizing tabular data associated with analyses of proglacial geomorphic change presented in Anderson and Shean (2021). The included zip file contains three CSVs summarizing volumetric change, Landsat NDVI values, and longitudinal profiles along valley floors presented in that publication. Each CSV has an associated metadata file contained in the zip file providing details of individual datasets.
Nisqually Valley below Nisqually Glacier, as seen from station 3 in 1934 prior to the October flood (date estimated). Note the substantial stand of trees and brush on the west part of the flood plain and the river on the east side of the flood plain. Mount Rainier National Park, Washington. Photo by USGS Conservation Division, 1934. Panorama in two parts. Photo 46 and 47. (seevfm00047) Figure 36, U.S. Geological Survey Professional paper 631.

Nisqually Glacier,
Upper reaches of Nisqually and Wilson Glaciers as seen from station 13 on August 30, 1957. Most of exposed bedrock areas marked in photo no. 18 are now covered by Wilson Glacier. Glacier surface at profile 3 is only 3 feet (1 m) higher than in 1949, but near left edge of picture it probably is about 60 feet (18 m) higher because at profile 2 the ice level rose 97 feet (30 m) from 1949 to 1957. The crevassing appears much coarser (rougher) now and extends to the east edge of the glacier. Exposed face of the ice field above the cliff is thicker. The falls at far left are nearly dry (compare with photo no. 18). Note the different layers (ages) of firn exposed in the small area at lower right, which can be differentiated...

Nisqually Glacier,
This data release is a repository for data presented in Anderson and Shean (2021), a publication looking at topographic change in proglacial and glacier-marginal areas on Mount Rainier between 1960 and 2017. Datasets include all newly derived digital elevation models, shapefiles defining various areas of analysis, and tabular summaries of data presented in figures. See individual child items and original publication for more details.
The Nisqually Valley below Nisqually Glacier, as seen from station 3. Aggradation on the flood plain, caused by the outburst flood of October 25, 1955, is evidenced by altered topography and dead trees. A new bridge was constructed high above the flood-affected channels. Mount Rainier National Park, Washington. August 31, 1965. Figure 38, U.S. Geological Survey Professional paper 631.

Nisqually Glacier,
Nisqually Valley below Nisqually Glacier, as seen from station 3. West of the island of trees, most of the vegetation present in the 1934 view (photo vfm00046) is gone, due to the glacier outburst flood of October 1934. The river now flows west of this island of trees. The deck of the concrete highway bridge used prior to the October 13, 1932 flood is visible on the flood plain just below the island of trees. Mount Rainier National Park, Washington. August 25, 1947. Panorama in two parts. Photo 46 and 47. (see vfm00046) Figure 37, U.S. Geological Survey Professional paper 631.

Nisqually Glacier,
Lower part of Nisqually Glacier as seen from station 5. Approximate locations of the surveyed cross profiles are shown. The entire glacier is receding. The area down-glacier (lower end of the white ice) is stagnant, as indicated by hummocky, debris-covered, non- crevassed ice. Note the long moraine-like ridge of debris-covered ice immediately to left of the white ice. The nunatak is bare. Note the debris load on the right half of the glacier downstream. Mount Rainier National Park, Washington. August 31, 1942. Panorama in two parts. Photo 22 and 24. (see vfm00024) Figure 20, U.S. Geological Survey Professional paper 631.

Photogrammetrically Derived Digital Elevation Models of Mount Rainier Proglacial Areas, 1960 to 2017
This repository contains a suite of digital elevation models (DEMs), derived from aerial or satellite imagery, covering glacier and proglacial areas on Mount Rainier between 1960 and 2017. Data are available for the Emmons, Winthrop, Nisqually, and South Tahoma Glaciers and their associated proglacial areas. These data were used in Anderson and Shean (2021) to calculate DEMs of Difference (DoDs) and assess topographic change in these proglacial settings. Aerial lidar datasets used in that analysis are available through the Washington Department of Natural Resources lidar repository (https://lidarportal.dnr.wa.gov/). The DEMs stored here have been coregistered to the 2008 Mount Rainier aerial lidar dataset. Differencing...
Shapefiles Defining Areas of Analysis for Proglacial Sediment Studies on Mount Rainier, 1960 to 2017
This repository contains suites of shapefiles defining areas of analysis used in Anderson and Shean (2021). Three types of shapefiles are included, each bundled into a zip file: First, polygons delineating areas with elevation changes we judge to be overwhelmingly due to sediment motion (as opposed to snow or ice melt), used to calculate final volumes of change reported in Anderson and Shean (2021). File names indicate basin and DoD interval associated with a given polygon. Second, polygons defining areas used for averaging Landsat NDVI values. Third, regular valley-spanning cross sections used to calculate longitudinal profiles of the valley floors over time. Calculating the minimum elevation across these cross...
