There is some information about this place on other websites, but I have other resources to get my information from. When my history lesson is complete, I will post it. I am planning another visit sometime after the snow melts. I went last summer, but didn't give myself enough time to really explore. When I found it, the main road was under water. The beavers have made it impossible to drive down. I walked through the water, but it does get quite deep in some places and the bottom isn't solid.
Check back in a few months for the rest.
