Most of the country is too big for calling to do much good. It's not your typical call into a drainage and hear a bull answer and dive in. I watched a group of bulls bugling and chasing cows in there one day and never heard a single bugle and they were on the opposite side of the draw from me, what that meant for us was 4 miles the way a crow flys with over 8000 feet of elevation in really crappy cross country walking. We found a different route that was 5 miles one way and about 5000 feet of elevation, we made it halfway there through some super nasty terrain and it started snowing on us. We continued for a bit until we got to where we could see the elk again, about 2 miles left to go, it was already late afternoon and now we were watching them between snow flurries, we decided if we did get to the elk and fill even one tag we would spend several days packing out. We decided to turn back and didn't want to try to traverse the unknown nasty country in the snow, we arrived back at the trailhead where our vehicles were at about 2 am totally exhausted and defeated with 6" of snow, the drive was sketchy going back to camp.
Those elk ended up being in that spot a couple of days later as well and happened to be the only elk we saw the entire trip. We never made it across to them and ended up pulling camp early. We were not prepared for the challenges out there, the size of the country and the amount of deadfall and thick brush we were moving through. We saw wolves every single day and even had a pack of about 8 in our camp one night. If I were to ever go back I would take my floorless shelter and hunt off of my back and make sure I had time to pack out whatever we killed. Someday I would like to go back, it is beautiful country, it really makes you realize how small you are and humbles you very quickly. Every time we made a plan to make a hunt it ended up being more than we could chew, that country is very unforgiving and slow going. I still have never seen such great habitat and such a luscious place so void of game in my life, it was almost like something out of a scary movie. There was a ton of historical rubs and beds in the mountain but zero fresh sign, seeing and hearing wolves daily was cool but I feel like they totally decimated a once game-rich environment where we were at.
We went the third week of September and dealt with snow on several occasions. To be successful in there you not only have to be physically tough but you will have to be just as mentally tough as well!! Definitely buy a wolf tag, if you see one shoot it and skin it.
Personally I would find another unit to hunt, ID has some great opportunities, there is a reason having an OTC rifle rut hunt seems too good to be true.
