I am familiar with the unit, which rifle tag did they get. Quality or bull? I ask because weather is a significant factor once October rolls around, reserving camp sites gets a hit easier as well.
The unit itself is pretty straightforward, its beautiful country, pretty steep in spots, but not what I describe as "big". The majority of the unit can be glassed from a trail. And getting meat to the trail is certainly the toughest part IMO. There is some sections of rugged ground so use caution in those, and be choosy about where they die if its in the cards. This is an awesome hunt for first time "backcountry" hunt. Finding elk shouldn't be to hard, but do some homework and be prepared as they will get moved around.
Weather is a game changer, slide alder and and rocks that is just a pita when its dry and warm, turn downright treacherous in a hurry once the rain and snow fly. Be prepared, while not what I consider hardcore backcountry, its no joke in inclement weather. Also I have seen fog be an issue which really sucks. If looking for the best the country has to offer, be prepared to stay up there a couple nights and pray for nice weather.
Last year I was able to assist a father and 2 son team, it was their first backcountry experience and his first bull at 65. It was an October hunt and the kickoff storm to our epic winter. Honestly I was concerned, but having a idea.of where elk were from prior scouting, I concealed my doubts and we loaded up with raingear and wool,l. After a almost 2 hour walk in the dark, a couple bugles, waiting for fog to lift and seeing 5 bulls. 45 minutes after daybreak the gentleman was standing over a beautiful 5x5 and you couldnt have paid me enough to miss that moment with him and his sons. Good luck to them.
