GREAT FALLS, Mont. -- With arms outstretched, Larry Salois walks in slow circles on his mother's homesteaded property in blustery northern Montana. His eyes are fixed on the ground as his feet follow a cobble of rocks that form a faint, yet undeniable, circle about 10 feet wide amid tall prairie grasses. "This is a good one," said Salois, a retired UPS driver who grew up helping his family grow wheat, barley and cattle a couple of miles east of Cut Bank, which borders the Blackfeet Indian reservation. "You can see how the stones form a ring here ... and here ... and here." Salois was likely tracing the remains of an ancient teepee ring built hundreds, if not thousands, of years ago by the Blackfeet to anchor their teepees against winds that have battered this landscape for millennia. The rings -- some three dozen of them are on Salois' property -- have become a flashpoint in a battle waged by dozens of landowners to stop or reroute a $209 million power line that would ship Montana wind power to Canada and possibly the West Coast.
