Goldfield—Princess of the Mojave
May 2005
The sunbeams are winding their way through the snowclouds. I am rising out of Death Valley to engage in some reverie, a journey into times past. Prospect pits, phantoms from boom times’ extinct, appear on the side of the road. Soon, I enter the Bullfrog Mining District.

Gold Deposits in Skarn
July 2003
Skarn consists of coarse-grained calcium, magnesium, iron, and aluminum silicates formed by hydrothermal solutions, which replace limestone or dolomite near the contact with an igneous intrusion. The contact metamorphism is usually caused by an intrusion such as quartz monzonite, granodiorite, or similar rock type, which may or may not be mineralized.

Prospecting on the North Yuba
December 2011
The research I did for “Gold in the Slate Creek Basin” (September 2011 issue) found me chasing a channel out of the LaPorte territory headed towards the old mining town of Brandy City, California.

Picks & Pans: Dredging After The Flood
March 2004
It was dredging season, 1997, after the catastrophic flood had hit us in January—a flood that took out bridges, roadways, undermined the railroad tracks in several places, and isolated us in the town of Quincy, California, for a week. The fog was so thick that planes couldn’t even land at the airport.

Gold in Panama
November 2001
Panama is a long, narrow isthmus, 30,200 square miles in area, that separates Costa Rica from Colombia. It is best noted for the Panama Canal, which is now under the control of the Panamanian government, aided by the United States. The canal bisects the country and is an engineering marvel that was opened in 1914.
