It took a lawsuit filed by the Public Employees for Environmental Responsibility against the Park Service and Federal Aviation Administration to get to this point.
PEER spokesman Jeff Ruch said the organization was pleased that Glacier was fading out tours altogether, but he said the Park should have gone through a formal environmental review process that would have looked at alternatives and taken public input.
Because as it stands now, Glacier will still allow the status quo to continue — up to 144 flights a year—until the sunset at the end of the decade.
