Jaeger City, California

Jaeger City, then in San Diego County, California, was the first and largest settlement near the fort until 1862.

It began as a stockade for defense of the ferry and its operators against the Quechan, and a collection of tents.

At its height it consisted of the Fort Yuma Station of the Butterfield Overland Mail and its local office, a hotel, two blacksmiths, two stores and other dwellings.

Jaeger's Ferry was rebuilt and Colorado City also, on higher ground as part of Arizona City, later renamed Yuma, Arizona, in 1873, and the ferry relocated there across from the fort.
