It's easy to walk among glaciers when it's warm. Head-high boulders dropped from the belly of the monster are commonplace. The whole top half of North America is one giant glacial scar. There's plenty of land up there to bulldoze, but precious little away in the globe's South. One piece of tectonic flotsam was stamped most effectively with U-shaped ice tracks. Huge hardrock wounded valleys. Like slug's trails, shining and not so sinuous. Thank melting for the glory of Fiordland. This year's high summer is long gone now.
