While in the UP (Michigan's Upper Peninsula) this year, in addition to wanting to make jam, I wanted to check out the remaining shaft houses. As time passes, there are fewer and fewer of these buildings remaining. So, I went out and took pictures of three of them. I think there is at least one more that I missed -- maybe more.
Next time .. maybe I'll have more time to look for more old buildings and ruins .. hopefully.
