Mine Hill, Roxbury

Visited Mine Hill in Roxbury, owned by the Roxbury Land Trust. it was much more impressive than its status as 'mere' land trust property might indicate. I immediately thought "state park" at least. 

 The remnants of the foundry, the roasting ovens, and the rest were amazing, as well as donkey paths up the mountain to abandoned mine shafts. Don't go in them, though - they are dangerous.
