Diamond

Though it's tucked into a verdant little valley just east of Malheur National Wildlife Refuge, Diamond has an average year-round population of something like seven people. You could probably do your own census as you take in the undisturbed cluster of a few houses and the hotel in the midst of this wildlife-rich, wide-open country. During its heyday at the turn of the 20th century, Diamond had a population of about 50, including the McCoy family ranchers, who continue to run the town's hotel today.
