St. Thomas, Nevada was founded by Mormon settlers in 1865. Thanks to receding waters due to the drought, we’re getting a look at it for the first time in years. In the 1930’s, construction of the Hoover Dam caused the nearby Lake Meade’s water to rise. As a result, St. Thomas flooded, forcing all of the remaining residents to evacuate completely by 1938. What’s left is a fascinating ghost town, a slice of life preserved underwater.
