Oregon Butte is the highest peak in the Blue Mountain Range of southeast Washington State. There is a lookout up there which should be staffed by early July. Beautiful spot, great views, and ample room to set up radio gear just about anywhere along the gently sloped ridge. I was there in late June and took advantage of the handy metal flagpole next to the lookout building to hoist up my antenna. Probably best to ask permission to do that when somebody official is around.
