Gleeson survived several fires and the 1918 influenza outbreak but it could not survive the combination of the copper ore playing out and the Great Depression. Unlike Courtland which declined in the 1920’s, Gleeson lasted well into the 1930’s. But like Courtland, the town had not diversified enough to become self-sustaining as most of the 500 residents depended on copper mining and moved on when the mines closed. The post office closed in 1939. A handful of people still live in the Gleeson area although the town site itself is not inhabited.

The boom and bust cycles for mining towns continued throughout the West. In some cases, the towns became ghost towns like Gleeson and Courtland. In some cases they survived to this day but as small communities like Chloride, AZ, or Searchlight, NV, with populations in the hundreds. Then there are the cities that not only survived the boom and bust cycle but thrived. Placerville, CA, and Butte, MT, are examples of communities that started as mining camps and grew to become diversified cities with populations in the thousands.

But it always has to be acknowledged that the towns like Pearce, Courtland and Gleeson are part of our heritage.
