Surficial geology for the Juneau area, hosted by ESRI. I used most of the geologic surface types of R.D. Miller, USGS, 1972, Some types were collapsed into broader categories: especially the many varieties of colluvial and raised-marine landforms. On the other hand, unit boundaries have been considerably adjusted and fine-tuned from 2013 DEM-generated bare-earth. Miller’s original map is available as a pdf from ADNR.
