This is a child item of the USGS Data Release: https://doi.org/10.5066/F7X63KF2 This dataset provides shapefiles and tabular data representing river channel geometries measured on photogrammetric imagery and extracted from a photogrammetric digital elevation model (acquired August 2021) along the Totatlanika River in central Alaska.

This dataset represents a digitized version of the Rawlinson 1993 surficial geologic map of the Flaxman Island and Beechy Point quadrangles, and portions of the Mount Michelson and Harrison Bay quadrangles at 1:63,360 scale. In this newly digitized version of the map, the original maps were scanned, georeferenced, and projected into GIS. Approximately 100-200 typographic and labelling errors from the paper version were corrected with inputs from the original author (corrections completed in 2024). However, this digitized product still adheres to the 1993 interpretation of the surficial geology. Original descriptions of the map units can be found with the 1993 publication (https://doi.org/10.14509/2484). The original...
