Here is an interesting geological survey I refer to often

Cool! 
This is the dataset I use on my maps (in addition to others that I took directly from old topo maps)
I have attached a PDF file that's included in that download which might be of interest

Awesome. They even included a few on the map in Vineland I’ve never seen actually documentedCool!

Here is another one I forgot about that is even more interesting. From 1928. It mentions operations local to me with names still being used informally today such as Tavern Rock and NJ Silica Sand. It also mentions Menantico sand and gravel co being located at Clark’s Mill rather than at Millville. Thought that was very interesting. It’s a shame another mill was ruined by sand mining.
