This small and otherwise entirely unremarkable city was at the heart of America's most infamous man-made natural disaster, the 1930s Dust Bowl. A combination of drought and bad land management resulted in years of devastating dust storms, forcing families throughout the region to head west on Route 66 looking for work. The impact that this eco-disaster had on the region (once known as No Man's Land) was brilliantly chronicled in the 2012 PBS series, The Dust Bowl.
If you go:
Boise City was one of only three known cities in the continental United States to be bombed during World War II, and there's a marker to memorialize the event. Another attraction worth visiting is the Cimarron County Heritage Center.
