I managed to take a nice ruff up that way last week after work.
Basically start heading up any of the side canyons. Look for draws with berrys, water, and thick cover. I look like I've been in a catfight right now from branches whipping my arms and cutting me.
The Eagle Creek drainage is a very good spot. I have seen lots of grouse up there.
I went out last night scouting some new terrain and seen a few new promising areas. Also did a death march up one of those hillsides

I'll be up in them tonight and hopefully come back with a heavier vest again.
