Link to zip file where geoTIFF bedrock files are located: http://danakarwas.com/bedrock_states.zip / One challenge in working with geoTIFF's is that they are huge, especially if they are at 1 arc second resolution. One Tile was about 25MB. My data processing involves stitching together two tiles (at a minimum) and uploading those directly to CUSP compute through Jupyter or as a single file on github was not possible due to file size constraints. The files were uploaded to a server that is hosted at danakarwas.com. This allowed for many large files to be stored.
