Alluvial Gold Mining
Alluvial gold mining. The Andes Mountains are rich in minerals, including gold. Over millions of years, erosion has carried gold down the eastern slope of the Andes and deposited it along river beds, leaving larger nuggets upstream and finer grains downstream. The tropical rivers have meandered constantly since the Andes began forming about 40.
