It's great you have so many choices. In the western mountains once you're above the foothills the choices are all softwoods that in themselves don't lend a distinctive flavor and in the case of pitch-wood, can give an off-taste.

Farther down the hill are oaks, so hardwood cooking is possible. Same in the coast ranges (but will guess it's pretty picked over in the popular spots).

In Scouts our standard camping area had alder and cedar and while we weren't sophisticated enough to do cedar-plank salmon (hard to keep the hotdogs from rolling off) the alder was wonderful for cooking. Usually wet though, since this was western Washington.

Cheers,
