I was surprised to see how far these hungry canines have spred. defenders.org has a trust fund that helps to pay ranchers for livestock that wolves have killed. While researching their site, I noticed they have made payments to most of Wyoming, Idaho & Montana . Southern Wyoming and Northern Utah have also received quite a few payments. I know they are in Colorado now but Colorado could have a lot more wolves then we realize. Rock Springs, WY has been getting payments for many years now and Utah and Colorado isn't very far from there, matter of fact, some of the best trophy elk areas in the west are in that area, like Colorado's 201,1,2 & 10. Utah's Three Corners & Diamond Mountain Unit.
