Can't help on that particular area, but hope to draw someday on my own. Two of my hunting partners were just north of there back in Feb hunting aoudad tho. Saw very few deer in a week, and the ones they saw were in canyon bottoms near water and cover. Lots of sheep tho, and I believe your son can shoot unlimited exotics there on his hunt also. Might turn into a great canyon hunt for them instead. Get on top and walk the rim edges and glass a lot. Your rifle choice would be great for that. Good luck.
