Snow geese deaths from mine pit number in the thousands
BUTTE, Mont. — Several thousand snow geese died after a snowstorm forced tens of thousands of the migratory birds to take refuge in the acidic, metal-laden waters of an old open pit mine in Montana last week.
But the toll could have been much worse, said Mark Thompson, environmental affairs manager for mine company Montana Resources. Along with the Atlantic Richfield Co., Montana Resources is responsible for Berkeley Pit, a Superfund site in Butte.
