In reply to frqnt:
Must have reformed in the past weeks. It cracked all the way accross easier in the season.
Access for Rive droite is hard. I've been there once and we ski'd from the top of the GM onto the Glacier then hiked up the moraine on the other side. From there you traverse (on the snow, on ski's) all the way past the routes to a cluster of trees above some cliffs. 2 abseils takes you down to the bottom (more or less) of shiva. Not the safest approach in the world but beats going up the lower glacier underneath the seracs!! Rive Droite gets to much sun at this time of the year though. It would need to be a baltic day IMO.
