Hello Eric, Thank you for the information. I am trying to dig up more history on the Ferris Fork Thermal Area but so far the going is slow. And right now I can't answer your questions, I hope someone else can. This was my first trip into the area. Jim Holstein visited in 2008, 2009 and this trip in 2010 but I think 2008 was his earliest trip. If I dig up more info I'll post it. Anyone else have any Info on the area?
