Looks like that stream is cut into glacial outwash.....the boulders would have started life as glacial moraine.

The geologist's eye!
Those boulders were left behind when the Rhône Glacier started to retire about ten thousand years ago (after having been there for about 14000 years).

This is where the water gathers and the boulders come from:

The so called Illgraben, Wallis, Switzerland

The scenery is located here.

And here you can see a few pictures more.

Those boulders were left behind when the Rhône Glacier started to retire [...]

Oops, well... actually not.
The retiring glacier just left behind a U-shaped valley. The rock formation in this zone is quite complex and consists of quartzite, chalk sediments (24-37 mio. years) and dolomite rock. The boulders were just eroded away by the water, and the stream in the video is cut into the material it has brought down itself during the last 10000 years.

You do realise Marcus that you've just done the equivalent of talking dirty to a geologist don't you? Just don't make a sentence containing either of the words rocks and off, it's tantamount to a marriage proposal.

I don't realize anything Nick, I think I don't even exist, I'm just an optical illusion.
