Probably was the DAKOTA BOYS trying to keep up their skills for the Gold Rush series... hehe
We see similar things on-going here in Virginia just East of the Blue Ridge Mtns where a known 20-mile wide gold field is that runs from Virginia down into North Carolina... Lots of Virginia towns with the word GOLD in their name...
Guys say they are not finding anything big but that sure looks like fun watching them go through all of that just like the GOLD RUSH SERIES on Discover Channel... Another good excuse for camping OFF-GRID hehe...
Yup gold mining in Virginia...
