I hope you haven't wasted your time looking for elk on Gum Hill. I live in Enterprise and asked around tonight and nobody has ever heard of elk on that mountain. I hunted deer there on the muzzleloader and know several others that did and only saw a few deer, let alone an elk. Don't get me wrong there might have been at one time but I have never heard that. There's no water on top unless you drop down towards town or cross highway 18 and driving that road everyday I sure hope there's not an elk in the road. From what I understand there was a nice bull taken by gray's ranch on the archery hunt. I'm going to try and get more information but I've heard it might score 380+. Try between there and Atchinson mountain. It's a lot of country but there in there somewhere. Also, west of Enteprise along the nevada border there is a small herd but you will be competing with a lot of other hunters and very few elk. Of course, that's how the entire unit is. Good Luck.
