Check out gatewayguiding.com. They hunt in the Brooks Range. Were advertising a mid-August hunt a couple of weeks ago and indicated some September hunts when at the convention in Tunica. They took a 45" ram in the Brooks about 4-5 years ago. I would be interested in what you put together and how it comes out. I can be contacted at email@example.com.
