I'm happy to report that the Forest Service has erected a new more permanent sign at the site of the "Dances With Wolves" winter campsite in Spearfish Canyon.
Older wooden signs have marked the spot, but been vandalized or stolen. I think this one will stand the test of time much better.
For those looking to locate the site, it is 3 miles from the Spearfish Canyon Lodge parking lot on the gravel road that passes by Roughlock Falls. GPS Coordinates are N44 20.288', W103 57.564'. If traveling from the lodge, there will be a small gravel turnout on your right hand side at the 3-mile mark.
