The Palomo mine Huancavelica Department, Peru.
Since 2000 the Palomo mine has sparingly produced excellent and distinctive specimens of realgar--the author of this article brought a fine lot of realgar specimens to the 2007 Tucson Show. Since mining formally ended in 2000, a few remaining miners have concentrated on recovering specimens, and good examples of...
Chalcocite and associated minerals from the Flambeau mine, Ladysmith, Wisconsin.
When the Flambeau copper mine opened near Ladysmith. Wisconsin in 1993 no one would have guessed that it was destined to become a world-class mineral locality.

Siding.
Siding A disused rail siding, the grass-covered platform a sharp-edged mound of earth. Loose clunks of coal, patches of brown dirt, the gums' sparse shadow. At the edge of the bush, crow calls shush the wheeling, rusting song of magpies. The odd car fizzes past, thirty-somethings behind the wheel...
Reclassifying class in today's Britain.

It wasn't my house, it was my parents'--a two-story Victorian built in 1890 at the height of the mining boom, which lasted long enough for the town to build an opera house and a hotel and a dead-end train track, long since removed. When gold and silver petered out,...
There is no alternative: exploring the options in the 1984-5 miners' strike.
Introduction In the early 1970s, Britain was swept by a wave of militant industrial struggle, the depth and political character of which had been unprecedented since the 1920s, both in terms of the sheer scale of strike activity involved, and because the period witnessed some of the...
Now is the time.
"In all, the Bush administration abandoned or delayed implementation of 18 proposed safety rules that were in the federal Mine Safety and Health Administration's regulatory pipeline," reports Joby Warick of The Washington Post. But there are signs that the folks at MSHA are feeling guilty. A couple of the...
Ages of O'odham architecture.
The first inspiration for this paper was a Papago, or Tohono O'odham, man who, twenty or more years ago, told me how much he admires the Hohokam people who preceded his immediate ancestors in the southern Arizona desert. The Hohokam were rich in water, he said, but his parents,... | |
