"Unearthing History: Exploring the Olde Stone Quarry of Sturgeon Bay, Wisconsin" 

BEAUTIFUL! Another part of Door County that I did not know existed. I'd have never thought that Door County had that industry in the past. Thanks Mark and Company for that wonderful look at history.

Nice to be able to see what is up there, I have lived here 20 years and never knew how much was actually above what you can see from the road. Thanks Mark,

Very nice video. The scale is impressive. And limestone seems to all around the great lakes. Thanks for this wonderful post.

That was a good one, Mark! I didn't know about this quarry. The most popular video on my channel is one about a quarry in Chicago. I hope this one takes off for you too!
