It's a tough time to hunt the N. Slope. Have hunted the muzzy hunt over there in both northern and northeastern regions for a long time. It's the most beautiful country there is that time of year. There are few deer though. Zeke's assessment would appear to be very accurate from what I've experienced.
It will also depend on which area you are hunting. There are different patterns between hunting the Bear River, or Henry's Fork, or Spirit lake, or Long's Park Dam, or going over by Red Canyon and Flaming Gorge, all the way around to Red Cloud Loop... The terrain changes and so do the deer's habits... Plus you're talking about a N. Slope that is some 80 miles long...
But like I said, we usually hunt it more for the love of the country rather than for trophy deer...
