Anyone know the location of scailet graille i think im very near it but gps data I have doesn't work so I'm hunting. Anyone know? Oh I've been to every boom shop in the vercors and not one of them has any caving guides including expe.

? Scialet Graille GPS: 31N 687058E 4982664N There is a very rough track which can be driven with care to a parking place at 31N 686823E 4982139N. Follow obvious path initially north and then north east up the side of the hill to the entrance. 10m entrance pitch to boulder slope down into large chamber with tatty formations. Scramble up on the left to second chamber with superb stal columns (take a camera). There is a further large chamber accessed via a hidden boulder choke. A good evening trip.

Note what the best-dressed caver was wearing last century.

Thanks for the help guys but no luck spent 4 hours looking for it gave up it's not easy to find every piece of info on where it is is wrong. My feet hurt I'm hot and I have a train to catch tommorow so given up. Gutted really wanted to see it.
