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." R.M.
