"The St. Croix Boom Site is a historic industrial property on the St. Croix River in Stillwater Township, Minnesota, United States, now developed as a park. From 1856 to 1914 it was the location of a critical log boom where timber from upriver was stored and sorted before being dispatched to sawmills downstream. The site was designated a National Historic Landmark in 1966 for its national significance in the theme of industry."@en . "105623.0"^^ . .
