A great NYT article on divisions over drilling and fracking on the Blackfoot reservation took me back a bit.
In another life, I was an environmental campaigner for something called the Badger-Two Medicine campaign, which aimed to stop drilling on USFS lands adjacent to the southern third of the reservation. These were lands formerly belonging to the tribe, and contained many of the sacred mountains in the Blackfoot creation myth. I could tell you truly hair-raising stories about hiking the backcountry there, and about meeting the Indians, grizzly bears and other residents.
The NYT article shows that the same divisions over drilling which existed in the early 1990s still exist today.
