You WILL see bears. They are thick as fleas in that area. It is a bear sanctuary. As for deer, I have seen some bruisers in there, but they were several miles from the nearest road. You had better love, and I mean dearly love steep terrain, because that is all there is dropping off down to slick rock. They don't name trails "stiff knee" for nothing.
If you hunt it, there will be some pressure within a mile of any trail head, but once you get past a mile or so, hunting pressure drops dramatically.
FWIT, between the fodder stacks is where I always saw the most deer and grouse. It has been many years since I have been in there, but I doubt much has changed. It is a vast expanse of mature timber with big rhododendron hells along the creek drains.
I have toyed with the idea of going deep and camping for a few days to hunt, but just have not had the gumption yet. The idea of getting a deer or hog out of there without a horse scares me a little.
