Another scan from the Canadian Rockies, and another semi-hidden road. It runs along behind the lateral moraine low on the flanks of the mountains at the left, visible intermittently where the moraine is a bit lower or the road is up a little higher. The road is unpaved, one-way, and strictly for the special tour buses (and I think pedestrians) that take visitors some distance up the glacier partially visible at the lower right. Where the buses go out onto the surface of the glacier the ice is about 600 ft (about 183m) thick. Far back on the Columbia Ice Field of which this glacier is a tiny tongue, the ice gets about twice as thick.
