Those grooves in the snow. Parallel. Ski tracks?
It depends how steep the slope really is. If it's as steep as Charlet (Woerth's guide) states, then they are probably tracks made by snow/ice/stones rolling down.

No. They are ski tracks. That's the sort of surface you get at the end of a fast run before people turn off and after the slope levels out. Nicknack and Mark have it right!
Edited to add: If you look at the 'horizontal image' in particular, you can see either the remnants of tyre tracks or of boot prints in the picture. Look towards the bottom left corner.
If it is the Aiguille d' Argentière, then they are unlikely to be ski tracks. Boot prints aren't unknown on snow slopes and the photographer was above Woerth.
Charlet states that the slope was forty five degrees. This matches the route description for the top of one route on that mountain. Hoever, even if the photograph was taken near the top, the camera angle grossly exaggerates the angle of the slope.
A possible clue is the strap apparently dangling from the left of his rucsack; if it's hanging free, the the slope is a lot less than it appears to be in the picture.
