This is considered North Sourdough. This side is a bit less used and it shows. Some areas can be a little overgrown, loose and technical. Going from north to South is climbing and South to North is more downhill. Lots of rocky trail with some short sweet flowy spots. Pads are a good idea as keeping a little momentum makes it ride better but can get out of hand real fast.

Great fat bike trail, especially from Peaceful Valley to Beaver Res Road.
