The Dustin Massacre memorial is located just West of Littfin Truss, on the North side of US Highway 12. Here is a little more information on this event, 29 June 1863:
Albright's Mill County River Park is an abandoned mill and mill race. It is a bucolic site with all the amenities: a picnic table, an outhouse, and a rope swing into the North Fork of the Crow River. What's not to like? It is just off County Road 5 about 4 miles North of Highway 12, where the Crow River runs under the road.
Middleville Township even has it's own 'ghost' town. This marker is off 49th Street SW, just West of County Road 5 on the North side of Smith Lake. That's Smith Lake in the upper right corner of the picture.
