Thanks Wolfman.

Every five years or so I visit the Columbia ice field in the Canadian Rockies between Banff and Jasper. I first visited the glacier field in 1963.

There is now a sign in the middle of a field of glacial rubble marking where the location was in 1963. It is a very long walk from there to where the ice is today.

It is a very long sad walk.

Not that it is melting. Climates change. But the degree of melting within the scope of a single human lifetime ... very very sad.

This link illustrates it reasonably well.
