Yep, very much like the Elkhorns.
It's north of Helena, the area is kind of bisected by I-15.
I think it's been about ten years or so (not sure of exact date) since it went to permit-only for brow-tined bull and there is starting to be some really good bulls there. General tag is spike-only.
An aquaintance killed a bull in there that went about 350 last year and saw one that was bigger. Odds are much better than the Elkhorn area.
