If at all possible I would go up early during the end of rifle deer season and ask some hunters if/where they have seen elk. Let them know what your reasons are and Ill bet a few will share some info. Small talk goes a long way with alot of hunters.
Another idea is to go talk to the guys at the Ranger station. They used to be fairly willing to share some info.
I used to deer hunt up there and still elk hunt it every couple, Some years they are where we like em in big numbers other years they are spread way out. We hunt within the road closure area.
Pray for a little EARLY snow!
