History

Topock was originally called Mellen, a railroad station and steamboat landing, at the site where the Atlantic and Pacific Railroad built the Red Rock Bridge, a steel cantilever bridge across the Colorado River in May 1890 after three of its earlier less well-built bridges had been washed away by the river upstream at a poorly chosen site at Eastbridge, southeast of Needles, California. The town was named for Captain “Jack” Mellon, a 40-year veteran Colorado River steamboat captain and an owner of the Colorado Steam Navigation Company, though it was misspelled as “Mellen”. From 1903 to 1909 Mellen had its own post office.
