I'm a bit slow on this.

In the June, 2006 issue of Backpacker Mag, there is a feature on the 3 'classic' long hikes in the US - Pacific Crest, Continental Divide, and Appalachian Trails. The main feature of the stories is a 4 page (for each) 'map' which positions the trails and the geography - obviously not very detailed. On the maps are comments that highlight, and offer descriptions of various parts of the trails.

On the map for the Pacific Crest Trail, there is a section between Mt Adams and the Columbia Gorge labled the 'Dark Divide' with the following comment (p 68):

'Dark Divide: Name given to the area between the Columbia River and Goat Rocks Wilderness, and reputed stomping grounds of Sasquatch.'

That phrase was used in the subtitle of Robert Pyle's 1995 Bigfoot book: Where Bigfoot Walks: Crossing the Dark Divide. (A good book for your library.)

That Pyle book is great. Not at all your typical 'bigfoot book'. I loved it.

I agree. A good outdoors book on the PNW. Plus a few hints of bigfoot activities.
