What stands out about Sonora’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Sonora began as an L&N Railroad construction camp known as "Bucksnort" in the late 1850s. This name is believed to have been inspired by the sounds of early locomotives, which the workers thought resembled deer snorts. When a depot was established at the site in 1859, the name was changed to "Sonora". This may have referred to Sonora, Mexico, the home of a railroad contractor.
U.S. Navy Master Diver Carl Brashear was born in nearby Tonieville and raised in Sonora.
