What the record shows
The federal survey describes the site: former town in Muddy River Valley, now covered by Lake Mead
Started in 1865 by Mormons from the Muddy Mission. Named for Thomas S Smith, president of the Mission. Last county seat of Pah Ute Co, AZ.
Saint Thomasappears in the U.S. Geological Survey's place-name archive as a historical populated place — a settlement that once carried a name and no longer does. Our editors are verifying its full story against census records, newspaper archives, and county histories; this record will grow as sources are confirmed.
Before you visit
Unverified sites may sit on private land, and coordinates from historical records can be imprecise. Verify land status and access before traveling. Take photographs, leave nails — removing artifacts from federal land is a crime.
