Gold Placers in Italy

Detecting Alluvial Bench Deposits

Heavy Glacial Rocks and Gold in the Midwest

Detecting for Gold: A Return to Familiar Ground
I probably swung over a few targets without noticing them. My first target came about ten minutes later as I went over a part of the high bench in this wide section of the dry wash.

Moore Creek, Alaska—Then and Now
The gold was very chunky and much of it had quartz attached. Even back then I knew that the gold was very close to its source.
