Big Bend, Big Hill
Given the terrain through which it winds, most of the Icefields Parkway is remarkably "well behaved": it's pretty flat, and there are few treacherous areas or steep climbs. One notable exception is a section near the far northern part of Banff National Park, where the road climbs some 700 feet in a short distance. To make this possible, the road bends back on itself in a hairpin turn called the Big Bend, which rises up the uninspiringly-named Big Hill.
The names are dull, but the view is not. This panorama looks south after climbing the hill, showing the parkway snaking far below. This is a classic "U-shaped" glacially-carved valley. I believe the large sloping mountain on the right is Mount Saskatchewan.
