Lots of hiking and slow down and hunt hard when you find the elk. That is some thick stuff up there and the Elk don't move to far if you push them a bit. Do tons of pre-season hiking / scouting in the areas you plan to hunt to verify elk locations. Don't hunt over old sign. Keep moving until you find fresh sign, and then hunt the area hard. They can be 30 yards away and you would not know it in some of that brush.
Remember that Elk travel along repeated paths unless pushed. Find their travel areas and work them hard. Learn their bedding and travel habits and hunt them where they are vulnerable. Make sure to make an appointment and sit down with the local elk biologist with Fish and Game. Have your questions written down and be thorough on getting full answers. Check the fish and game website for units and areas where the kill to hunter ratios are good, and don't e afraid to hunt where there are few hunters and low kill ratios, that is so long as you spend enough time scouting to know there are lots of unpressured elk in that area.
I often kill elk in areas where I don't see anyone else for days. The elk are not spooky and are easy to call in.
