Welcome to the Great Underground Mineral Show. Straight from the old drains of Minneapolis and St Paul, hidden where the sun never shines,resides some of nature's wonders, MINERAL DEPOSITS! Some are big, some are small, some vivid in colors, some are not. Now sit back and enjoy the show.

Cool pics, all that orange shit can get annoying when draining, one pair of my shoes is orange now because I took them draining and am too lazy to clean them.

I've moved this to the Great Lakes. It seems far more relevant to the area than belonging in main.

It's lovely, though. I love drain mineral deposits

None of that can be real. Everyone knows it takes thousands of years for minerals to accumulate like that.

but did spiderman come out to play??

Nice calcification pics!

Good work! I've yet to see a local thread done like this.

Then maybe the MSP drains are much much older......;)

No radioactive super heroes, but I did meet Anubis

Urban geology ;) Nice work Herm. I like 13 and 22 the best I think.

Some of these lovely pictures cause the line between mineral and fungus to become slightly fuzzy. I think the slightly mucus-like ones are my favorites. Thanks for the slimy tour!
