The life of a glacier is hard, my friend:

Sleeping on rock beds and just scraping by.

Many will meet a warm, watery end;

People climb mountains to find out just why.

Almost six-hundred kilometers square,

(Larger than all of dear Rockland County)

Down in New Zealand (yes, way, way down there!)

Pukaki dumped a bouldery bounty.

These gorgeous moraines, through blood, sweat, and tears

Tell us a tale of beryllium ten:

Wind the clock backwards thirteen thousand years,

The old Southern Alps were colder back then.

On see-saws it seems the blame has been pinned ...

Answers may blow in the Westerly wind.
