Transcribed Notes: Bureau of Reclamation typed notes appended to back of photo: Boulder Canyon Project--Nevada--Region 3 St. Thomas, Nevada, was founded by the Mormons in 1855. In its heyday there were about 800 residents in the village. The "Main Street" was a part of the old Arrowhead Trail, which led from Salt Lake City, Utah to Los Angeles, California. In June 1938 the town was abandoned by its residents, which at that time were few in number because of the rising waters of Lake Mead that submerged the townsite. In 1945, after having been flooded for 7 years, receding waters of Lake Mead revealed St. Thomas much as it has appeared in former years. This photo was taken looking toward Mormon Mesa. The receding waters of the lake can be seen in the center of the photo.
