I wouldn't waste my time at McFarlane, was up there last week and went past Toltec with trax and way up the Esterbrook road as well...not an elk track to be found. Glassed the hell out of that area and zippo. I would go no farther North than Pinto creek if it were me.
Had a high school buddy and his cousins hunt last week, spent 4 days prowling around, say maybe 500-600 elk and got 3 killed, 2 from one herd. Got lucky on the first one, found a herd and a landowner stopped and gave us permission as they were just across the fence from BLM.
Probably 300 in this herd, buddies got 2 with 2 quick shots, 116 yards and 150 yards:
Day before in another area, 30 or so in this bunch, buddy shot one at 585 yards, one shot, no wind, wide open without a tree in sight:
