Yes it is very thick. It's not the most enjoyable elk hunting but alot of N. Idaho is the same way. The elk don't stand out in the meadows in the morning and evening anymore like thaty did 15 years ago. Just have patience and maybe invest in a trail cam right before bow season and move it around in drainages until you see some sign. I find the elk in that area tend to be in the 4000' elevation during rifle season. Also as thick as it is, the elk don't really like it anymore than we do. Ther is old grown in logging roads they use to travel look for ones that aren't completely overgrown with alders that are close to water and take a hike. You are bound to run into them sometime. If you take the pass road that goes over to Priest from Sullivan right at the border on some sharp corners you can see a few non accounted for on map trails that head up some open stuff. I have seen lot's of elk about 3-4 miles from there. Also look into the Salmo loop trail. that's a good starting point. It's about 8 miles to the end but you can hunt every drainage off the divide, just pack a tent, light bag and the rest of you gear in and set up a spike camp. Do some scouting earlier in the year and if you find elk, start hauling in supplies and hide or bury them(especially water). Just get in the best shape you can and hope for the best. I don't use them but horses or mules would be helpful. If all else fails, cough the $600.00 bucks for and idaho tag like most of Spokane does and go hunt up the north fork of the cda of joe and see the trailer park like camps. Typically in these areas peopled push elk herds from one camp to the next until eventually someone get's a shot. I backpack hunt to stay away from this and have been way more succesful. Once again, good luck! If you have anymore ?'s on the medalline/Priest area don't hesitate to ask, I will give the best info I can. Good day.
