You're hunting the southern end of the Beaverhead RANGE which is part of the Beaverhead-Deerlodge (significant because of the size of the NF itself).
I take it you're hunting 321? Good opportunity with the ability to take a cow, but a lot of those elk will bug out to Idaho once the shooting starts if the weather hasn't pushed them out already.
Can be a tough go where the lodgepole is thick.
