After heading out to the bar late last night, it was great to sleep in a touch today, leaving the hotel at 9:00. We all hopped into a mini-bus along with a guide and driver and headed back into the Los Glacieres National Park, this time along Lago Argentino around 200km south of El Chalten. Los Glacieres National Park was the 3rd national park in the world, behind Yellowstone in the US, and Banff in Canada. Down here in Patagonia, there is a real feeling of being back home. There is the same clash of mountain and flatland culture. Patagonia was explored in the late 1800s and settled by European immigrants shortly afterwards. There are strong familial ties to Croatia, Scandinavia, Germany, and Austria, all with a Latino flair. Lago Argentino is the largest lake in Argentina and was named that by Francisco Moreno (who’s nickname was Perito meaning “expert”) who was sent to map inner Patagonia and mark the border between Argentina and Chile.
Lago Argentino is home to over 200 species of birds. Many of them stay there from October to March and migrate north for the winter (it was weird to hear that, as well as type that) some as far north as Canada.
After a couple stops along the lake, we made our was into the park and to the first viewpoint of the glacier.
The Perito Moreno Glacier is very different as it is one of the few in the world that is in balance (not receding, as nearly all in the world are, or advancing, as two in Chile are). It is moving just over 2m per day with the snow in the icefields adding to the ice that flows to the lake over 500 years. The glacier is about 50° south of the equator (about the same distance as Calgary is north of the equator) yet is in far better shape than what we have at home. The Patagonian Icefield is the 3rd largest icefield on the planet (behind Antarctica and Greenland) and fairs better due to the amount of precipitation. While the Antarctic and Greenland icefields have much colder temperatures they are deserts, and the Patagonian Icefield has 10-12m of snow per year. This snow presses down on the snow below, compacting, forming ice, and becoming a glacier. So even though there are massive losses as the glaciers calve into the lakes (Argentina) and ocean (Chile) they are replenished from all the precipitation on the Chilean side of the border.
On the bus out, our guide did a great job explaining why there is so much more precipitation here in Patagonia than Calgary or Brussels on an equivalent latitude. And the answer is geography. The majority of all landmass is in the northern hemisphere, and aside from the south island of New Zeland, there is nothing as far south as here. Thus all precipitation from the southern Atlantic, Indian, and Pacific Oceans is focused here when everything is forced up over the Andes.
The visitor centre to the park is done up very well with good quality catwalks delineating where visitors can walk and observe the glaciers. Where the glacier meets the lake ranges from 60 to 100m above lake level, with an additional 100m below the water’s surface. There were a few catwalks to go and explore, but we found the best was just staying at the lower viewpoint, waiting and watching for ice to calve.
The place where the glacier meets Lago Argentino is at a peninsula separating a bay from the main body of the lake. This allows 3 fronts of the glacier to be seen and was truly spectacular.
We were back to our great Patagonian weather luck with only a light breeze and the temperature in the low 20s. This was great for calving too. It was hard to gauge how big the pieces of ice were that fell as the sound was so enormous. A small chunk (which was probably the size of a couch) would overshadow any conversation, and a large 60m tall sheet was almost deafening. And the wall of ice echoed and amplified everything.
After watching the glacier calve for over an hour, we headed up to the visitor’s centre for lunch then down for a boat tour of the southern face. The views were really good and the lighting produced some fantastic colours of blue and white, but we didn’t see any large pieces fall.
Pretty much everyone slept on the bus ride back to El Calafate, but then it was out to the Glacier Museum. The group of us decided we had heard enough about ice and didn’t want to see the 3D movie, so headed straight to the Glacio Bar that was all made with glacial ice (including the bar and cups). It was a balmy –8C but our friend from Los Angeles found it very cold.
It was an open bar for the 25 minutes you were in there so we went through a few vodkas which made sense in the ice glasses. I decided to remove my parka and gloves to show off my Canadian pride for cold weather enjoyment.
I figured I had been to a few CFL games that were colder. After some indulgence, we headed off to a pizzeria for a quick and early dinner (with malbec of course) before packing (with another malbec) for our travel day into Chile tomorrow.
