Onward, northward. After making arrangements for transit and getting food and fuel, I set off for Torres del Paine. Torres del Paine is a jewel of a national park.  Within its 700 square miles there are mountains, forests, glaciers, creeks and waterfalls and incredible views. My plan was to do a 4 day backpacking trip exploring three valleys, the "W" trek, so named for the shape of the route.

Travel into the park from Natales is a half day enterprise involving buses, catamarans, and finally, feet.
 


From the catamaran across Lago Pehoe. The glacial lakes all are in mind-bending shades of green, blue and aquamarine.



Heading upvalley, the peak of Paine Grande records a bit of precipitation.



In ready supply in case anyone needs to slow their heart down.

Lago Grey, and iceberglings. There is actually a very precise terminology for the classification, description and taxonomy of floating ice.
Pictured above are an assemblage of "growlers", "bergy bits" and a "small".

My first glimpse of Glacier Grey, a massive source of ice cubes that forms the southern end off the Southern Patagonian Ice field.
The Southern Pat, by the by, is the third largest  continental  ice field.: Antarctica, Greenland and SoPat.

 Retreat? You betcha. The glacier used to almost surround La Isla o Nunatak, that larger scrap of land caught between ice and water in the above photo .





Murphy's Law of photography.  I sat on a rocky outcrop for several hours, watching and listening to the glacier.
 I ran through the various lenses I had with me. And wouldn't you know, the glacier decided to calve when I had the widest angle lens mounted.

So there, from afar, is some geophysics in action.
