I'm interested in approaching Cape Horn (Northumberland, N.H.) via snowmobile trail 5 from Page Hill Road. (I'm aware of the more common eastern approach from Lost Nation Road, but I'm not enamored of it.)

Anyone done it this way in summer? What's the trail like? Is it a woods road, or an grass-overgrown corridor? What is Dean Brook like to cross if I leave the trail early and head straight north? Are there swamps?

I like the idea of this approach since it is dead level for much of the way.
