Keane Wonder Mine

This boom slowed as a result of the Panic of 1907 and paused when the area was designated a National Monument by President Herbert Hoover.

Keane and a partner named Domingo Etcharren had scouted the area, called Chloride Cliffs, and had located a potential silver mine.

[2] Homer Wilson moved to the mine site with his family, and created two towns in the area called Keane Springs and Chloride City, California.

It was limited only by a lack of water and the extremely high heat in the valley, which forced Wilson to have the miners work at night.

However, the mine was embroiled in a long legal controversy after a financial maneuver involving the failed State Bank and Trust Company of Nevada.

Both of these structures were popular with tourists, but have suffered from neglect, but the National Park Service reopened the mill and mine site to visitors in November 2017.
