Death Valley National Park in Inyo County, California — The American West (Pacific Coastal)
Keane Wonder Mine
During the first two decades of this century the Keane Wonder Mine was the scene of major investment and development. The products of this labor were the riches - gold and silver.
About 1903, Jack Keane, prospector, discovered gold in this area of the Funeral Mountains. The ore was of such high quality the mine sold for $150,000 before any development had started. In late 1907, the Keane Wonder Mining Company completed construction on an aerial tramway and mill. (This photograph represents how the mill and lower portion of the tramway looked in 1907).
The tramway, consisting of eleven wooden towers, transported ore from the mine to the mill, a distance of 1 mile (1.6 km) and a drop of 1,300 feet (396 m). The ore, carried in large buckets, moved by gravity down the tramway on cables which also provided mechanical power to operate the crusher up near the mine.
At the mill, gold and silver were separated from the rock by a stamp milling process. This operation can be compared to a nut (ore) being struck by a hammer (the stamp) whose blow separates the valueless shell (the quartz rock) from the valuable kernel
The gold, silver and some lead harvested from the mine and processed in the mill was hauled by wagon to Rhyolite, Nevada, the closet railhead. Even the famous steam tractor "Old Dinah" made a couple of trips pulling precious loads before breaking down on top of Daylight Pass.
During the peak years, 1909 through 1911, 73,989 tons of ore were processed yielding $682,209.69 - an average of $9.22 per ton. The mine was reported to have ceased operation in 1916, when "...the developed ore bodies were worked out." Reliable estimates have put the total production figure of the Keane Wonder Mine at $750,000.
Each piece of rusty mining machinery and every bit of timber represents a part of Keane Wonder's intriguing past. Please do no remove or disturb anything. Leave it for others to discover and enjoy.
NOTICE: There are many hazards associated with old mining areas. Use caution when walking around.

More about this marker. When we revisited Death Valley National Park in March 2016, the National Park Service (NPS) had closed the Keane Wonder Mine and surrounding area to public access. NPS cited several hazards including unstable ground, toxic waste and collapsing structures.
In 2017 the mine area reopened after safety improvements were completed, and a new marker was installed.
