"The mountains I chose were Washington's southern Cascades, a region of intense Bigfoot activity, judging by the density of reports over the years. Specifically, I zeroed in on a range of black peaks running crosswise to the main north-south axis of the Cascade volcanoes. The name Dark Divide applies both to this chain of impressive basalt extrusions and to the roadless area that surrounds it. The divide, which separates the Cispus and Cowlitz river drainages on the north from the Lewis River on the south, lies roughly in the middle of a diamond formed by Mounts Rainer, Adams, St. Helens, and Hood."
