Sure, lots of elk hunting in official Wilderness Areas. They are all part of a GMU. There is no separate elk season for elk in wilderness areas like there is with the early rifle deer hunt, but you can hunt wilderness areas with archery, muzzleloader, or rifle tags during the general seasons. There ARE a few "Elk Areas" that have rifle permits with a September season, such as the Goat Rocks, Carlton, and Mt Adams, but they are extremely difficult to draw.
