The source behind the name
USGS GNIS Populated Place names in all 50 states and DC. Features in the historical extract or explicitly named historical are excluded; duplicate decision records with identical identities and coordinates are collapsed. GNIS points identify names, not legal or neighborhood boundaries, current occupancy, school attendance or a statistical population. Nearby Census places and tracts remain separately named geographies. Name completeness and currency vary; this is not a claim to include every locally used neighborhood name.

USGS description & history
The name may be of Mohave Indian origin: 'Tohopau'. Originally named Needles in the 1880's, the name was changed to Powell for the nearby railroad station in 1883. In 1890, the settlement was known as Red Rock and Red Crossing but in 1903, a 'new city', Mellon, for John Alexander Mellon (b. 1842) who was a Colorado riverboat captain, became the official name. The placename corrupted to Mullen in 1915 but Topock became the selected post office name (AZ-T101).
