my dad took a 172 out of umptanum this year that was about a month after the bio told us he didnt think there would ever be a ram bigger than 165 come out of the umptanum, i think it helps if you scout and find out where the big rams are, we saw a lot of rams down on umptanum creek (i dont even think any of them wouldve gone 160), and near roza dam (one good ram but nowhere near 170) , but the big boys were all in one group several miles from that area (5 others with the one my dad shot and every one wouldve gone 160 pretty easily) and yet everyone was hunting down by umptanum creek and of the 5 tags in the umptanum i think 4 were notched that day, we were up where the big boys were all day getting my dads sheep out and never saw another hunter, and it sounded like most of the others were hunting down in umptanum canyon
