What steps did dawson go through to become a ghost town?

Dawson did not become a ghost town until 1950, when the Phelps Dodge Corporation shut down the mines. At closure, Mine 6 was the largest producer, and several other mines had been previously closed out because of declining demand. The closures were also due in large part to the completion of the twenty-five year coal contract with the Southern Pacific Railroad. The entire town was sold or razed, with some of the miners' houses moved to other locations.

The Southern Pacific branch to Tucumcari was lifted at about the same time, but was later rebuilt by the Santa Fe Railroad, continuing up the canyon to the York Canyon mines. These mines were initially operated by Kaiser Steel, with their output being transported to their steel mill at Fontana, California. The York Canyon mine was operated by several different companies, finally closing in the early 2000s.
