At a Glacial Pace

Three miles wide at the snout, nineteen miles long, filling the expanse between the mountains like builders’ foam; the powder blue ice, its hollows and crevices appearing backlit by the water within, juxtaposed with the deep green coniferous trees and the stark grey-black of the mountains, lightly dusted with snow and engulfed in low cloud at the margins; a wall of ice, striped with seams of deeper blue and black, rising an average of 240 foot above the surface of Largo Argentino, carved by nature into tens of thousands of tightly-packed columns ranking into the distance like an ancient army massed for battle.

The Perito Moreno glacier in the far South-West of Argentina feeds from the Southern Patagonian Ice Field which straddles the border with Chile and is the last redoubt of an Ice Age which ended 11,000 years ago. It sprawls over an area more than four times bigger than Manhattan or about two and a half times the size of Barcelona.

Boardwalks on multiple levels connected by stairs take visitors within a few hundred feet of the snout. Pops and cracks echo from around the glacier as if hunters were out on its surface shooting birds. Calved ice litters the waters around it.

Hours could easily be spent just gazing in awe at the glacier and listening to its cracks and creaks and bangs.  But I was not just there to look.

Three years earlier in New Zealand, I arrived in Franz Josef too late to be able to hike on the glacier, as I had hoped, and had to make do with seeing it from the foot of the mountain on my way to the bus the next morning. Now, on a different continent but back in the Southern Hemisphere, the chance had come round again.

I took a boat across the lake to the shelter on the shore by the South Wall, where I was herded into a group of about 15 and had crampons attached to my boots. Two groups were out on the ice already, one about a third of the way up, the other about a third from the summit.

In the middle of the briefing, there was a boom as if of a cannon and then a rumbling, shuttering sound like an office block succumbing to the wrecking ball. I turned and watched as a section of ice thirty, forty, fifty feet high detached from the glacier and slid vertically into the lake, rose again as pulverised fragments and caused a tumult in the water.

We started our ascent.  The crampons, impossible on land, were intuitive on the ice. We moved slowly, in file, behind the guide.  The route weaved between cracks and ponds and glacier mills, where surface meltwater spirals into a shaft in the ice. The ice glistened in the sun. We drank the coolest, freshest water straight from the glacier.

Then, at the summit, the first of the guides produced whisky and glasses; the other harvested ice from the glacier with an axe. ¡Salud! We drank the whisky tempered with chunks of Perito Moreno, packed up and made our way back to the shelter.
