Keane Wonder Mine

 mine, production

The Keane Wonder Mine produced about a million dollars of gold in the early 1900s.
Much of the Death Valley region was prospected and mined for gold during this period but only a few areas such as Rhyolite to the east, Skidoo to the west and this site produced much gold.
The mill sits on high grade metamorphic rock derived from the lower member of the Crystal Spring formation. These rocks make up a significant portion of the lower plate of the Boundary Canyon detachment fault. Included amphibolite was probably derived from the diabase sills and the marble from the limestone within the Crystal Spring formation. These rocks were probably metamorphosed twice: First and most strongly in the Cretaceous and less so during the Tertiary formation of the detachment.
