This project helps students explore geologic maps relevant to the Pine Ridge Reservation. It includes a guided Jupyter notebook, a bundled South Dakota geologic-map database, source links, and example output maps.
You do not need to know Python or use a command line.
- Install Miniconda if it is not already installed.
- Double-click
START_HERE.batin this folder. - The first launch installs the required scientific software and may take 10–20 minutes.
- When Jupyter opens in your web browser, click
olc_historical_geologic_maps.ipynb. - In the notebook menu, choose Run > Run All Cells.
The notebook explains each map and saves finished figures in the outputs folder. It downloads the Pine Ridge boundary and several map PDFs, so an internet connection is required. Large geologic-map downloads can take several minutes.
If the launcher reports that Conda is missing, install Miniconda, close the message, and double-click START_HERE.bat again.
olc_historical_geologic_maps.ipynb: the guided lesson and map workflow.data/SD_Geologic_Map.gdb: the bundled statewide geologic database used by the notebook.outputs/: maps produced by the notebook.environment.yml: the exact software environment.START_HERE.bat: the Windows launcher.

“Mission” is not a separate publication in the official South Dakota Geological Survey 1×2-degree series. The Mission area is covered by other map sheets listed here and by the intermediate-scale Mission map below.
These scanned maps were produced at different times. Treat boundaries and unit names as historical interpretations, and consult newer mapping where available.

- A download times out: wait a minute and run that notebook cell again. Government servers can be slow.
- A basemap is blank: the scientific map still works; the optional background map may be temporarily unavailable.
- The browser does not open: open
http://localhost:8888/labafter the launcher finishes. - The environment will not install: confirm that the computer is online and that Miniconda is installed for the current Windows user.
- You only need a PDF: use the tables above; Python and Jupyter are not required.
The notebook uses the SDGeology_20040630 layer in the bundled file geodatabase and does not depend on the retired USGS SGMC CSV URL. Recreate the environment with conda env create -f environment.yml, then run conda run -n olc-geologic-maps jupyter lab from this folder.
Source links were reviewed on August 20, 2026. Government sites can reorganize files; the official SDGS publications search is the fallback source of record.
