Canada’s treasured Jasper National Park could be on its way to gaining a theme park-like attraction. US-owned Brewster Travel Canada wants to blast out the side of the cliff beside the Icefields Parkway to build the Glacier Discovery Walk. This would be a walkway and a massive glass-floored "skywalk" extending over the Sunwapta Valley. This may signal the start of a renewed surge of commercial development within our Rocky Mountain national parks.
