    Hey, I think we have an answer for the mysterious web-shaped symbols, Stone Quarries. Who knew?! And it looks like the rectangular crosshatch is for coal mine.

    Found a legend for the plat maps at the State Historical Society of Missouri - Plat map of Cooper County 1877, at the bottom of pg.8

    Hooray! but I still like the giant spider theory, it does seem like hobbit country there.

    YAY! Perfect. Excellent work.
    I actually love the non-standardization of old maps. Makes for some really unique experiences.

    I had been wondering if it wasn't some drainage ditch. Most of the legends I found rendered quarries differently.

    Some examples, just because I find this stuff really interesting...

    Here's it more hatching, less defined.

    Sand and Gravel puts are more pit-like here, (Four down, three across.):

    This was REALLY common and was a big reason why I was looking elsewhere. For a long time, I wondered if it wasn't some sort of hydrological symbol, like a french well, or something.

    Shoulda done what Rwhyte did and went to the source. Excellent work.
