The Blackfeet reservation sits atop rich oil reserves that can only be tapped through fracking. Oil firms have leased nearly 1 million acres of reservation land – including along its western edge, next to Glacier National Park. The superintendent of Glacier has requested federal environmental review of all drilling on the reservation, citing risks to sensitive populations of grizzly bears, park air quality and the impact industrial oil operations on the park's spectacular views. Fracking impacts could also wreak havoc far downstream: Snowmelt from Glacier traverses reservation lands to join the Missouri River. More than 30 exploratory wells have already been drilled. A Romney administration would assuredly greenlight more.
