"South Pass City began as a gold-mining town in the mid-1800s, but after an initial boom, the population dwindled to just a few hundred people. It was designated a historic site in the late 1960s and 17 restored original structures reflect the continuing preservation efforts. The town's grounds and trails are open year-round, but in the summer, it's also possible to tour the artifact-filled buildings, shop in the old general store, or pan for gold in Willow Creek." - Travel + Leisure Editors
