Under normal circumstances, I'd suggest that this post is better suited for somewhere like /r/geology, but they're closed right now. I'm not personally that familiar with South Dakota geology (maybe someone else will chime in), but the first place to start is with a geologic map.

The geology map actually has nice little app. Source: over 1 year ago

Deck is very minimal and not really suited for anything beyond simple, personal stuff, in my opinion.
