Glacial Erratic Blocks in the Rhone Valley

Continuing our glacial explorations (see also The-pyramids-of-euseigne), we visited a number of enormous glacial erratic blocks in the wooded slopes above the town of Monthey in the Rhone Valley. These blocks played a pivotal role in the realization that there had been great Ice Ages in the past. There are eight blocks along a trail about 5km long between Monthey and Collombey. ( MT_Blocs_Erratiques_Web.pdf). The first and largest of these blocks, “La Pierre des Marmettes”, is now in the middle of the parking lot of the Monthey Hospital.

The Pyramids of Euseigne

The Pyramids of Euseigne are one of the more bizarre geological features created by the last ice age. They are in the Val d’Hérens, one of the southern side valleys off the Rhône valley of Switzerland. The entire Rhone valley and its side valleys were under glaciers at the height of the last ice age around 23,000 years ago. An old university friend who is a geologist visited Switzerland at the beginning of the year and invited me to join him for an exploration of some of the landscape features created by the glaciers of the last ice age.

In the photo below, my friend is looking south towards the junction of the Val d’Hérens and Val d’Hérémence where two glaciers met and continued down towards us. The pyramids are located on the ridge separating the two valleys, We are standing on the remnants of a glacial lake delta formed by the damming of the melt waters of the joined glaciers. The glaciers retreated about 11,000 years ago when humans expanded north back into Northern Europe and Britain again.

The Pyramids are the remnants of a ground moraine created from finely ground silt and sand with embedded larger boulders. Some of the boulders protected the underlying compacted silt from erosion, forming protective caps.

Méribel mountain views

Some photos of the French Alps from the Saulire on the mountain ridge between Méribel and Courcheval. The Saulire is at 2738m and has spectacular views of the surrounding mountains, including Mont Blanc in the distance 63 km away. And then a thousand metre descent which made for great skiiing.

A week skiing at Méribel

We went to Méribel in February for a week skiing. It is a resort in the French Alps about halfway between Grenoble and the Italian border. Last winter was not a great year for snow, but it snowed heavily just before we arrived and there was lots of fresh powder. The entire week until the last day was clear blue skies.

Snow on the pines

Thanks to the President of China, I spent a day in January skiing at Les Houches near Mont Blanc. Xi Jinping was visiting my organization, and we were told to avoid coming to work if possible, as the security arrangements were extreme. Juras and Swiss Alps were forecast to have low temperatures, low visibility and strong wind, so I headed up towards Mont Blanc where it was sunny and no wind. The temperature was still low at about -10 degrees C.

Parapente flight from France to Switzerland

Yannick has combined parapente (paragliding) with alpine climbing and has a tandem harness. He told me he could arrange two more pilots and my boys and I could do a flight over Mont Salève, in neighbouring France near Geneva. The boys were very excited, my older boy had been lobbying for several years to do a parapente flight. And Yannick is very experienced and I know he does not take risks. So around the end of August, off we went. All three of us launched from the grassy slope on top of the Salève out over the cliffs. I cruised around the cliffs and above them. Saw the boys from time to time, though they ended up going up to around 1700 m altitude, much higher than me. Guess I am a bit heavier.

Below is a short 2:30 video of my flight. In the second half of this video, I flew the wing for a while, then Herve did some acrobatics before we landed back in Switzerland.

Mont Pelvoux

Les Ecrins

I was cleaning up my photo files, and came across these photos from a trip in September 2012 to Les Ecrins, the southernmost part of the French alps, about 100 km south of Grenoble. There are a number of peaks over 4000m but our objective was to climb Mont Pelvoux, just below 4000m at 3946 m (12,946 ft). Bad weather in the Swiss Alps had led us to flee southwards looking for better weather. There was heavy rain all the way to Briancon, so we stayed down in the valley for the first night rather than climb to Refuge de Pelvoux in the rain. But that meant a big day the next day with a 2700 m climb to Pelvoux. We left at 3.30 am, amd climbed the 1200 m to Refuge de Pelvoux in about 3 hours, arriving just as the sun was rising.
