Thanks - just devastating. As if they didn't have enough problems with just logging. Mining with mercury is devastating to the landscape.

Saw a special on TV, (PBS?) a few years ago, it it showed the crazy meter square claims being mined by bucket and sluice over large tracts of land, thousands of registered claims.  The army was there as peacekeepers as it could get a little fractious with claim jumping and such.  As I understand it, the mining has shifted to direct high pressure hydraulic mines covering large swaths of land since that feature.

BTW, ever been to the area of California above Sacramento and Folsom?  Amazing the amount of damage that was done by 19th century hydraulic mining in California to Idaho and some other areas between the Coast and Yellowstone.

Not that I remember. 

But I have seen whole mountainsides filled with rubble from the gold and silver mines in the Colorado mountains.

Rock and shaft mining for gold is completely different than placer mining with hydraulic high volume destruction of hill and mountainsides.  Outfall rubble from shaft mining is almost beneficent by comparison.  The TV show currently on with placer mining in the Yukon and Colorado by dredge or dig and sluice shows alluvial mining at its most destructive, IMNSHO.

Reduction of ores to useable gold is the biggest issue with rock mining, sluicing and sifting placer gold is cleaner in that sense but mightily destructive of the raw environment.
