French SRT Anchor abbreviations - Help Please !

[Keith P]

Hello All,
Can anyone help enlighten me on the anchor abbreviations the Froggies use on their SRT Topos ?  OK I get it that AN = Amarrage Naturele (natural anchor), that S = Spit, that Dev = Deviation but what do 'B' and 'Y' stand for.  Nearest I can get to 'B' is that it means 'spindle'......is this a 'P' hanger ?  As for 'Y' I am totally lost.
For example, what would be your translation of the following (describing the 3rd main pitch in the Biefs Bousset route into the Doubs Verneau System) :

P17  2B  1B  > >  2BY V  C28  (OK, so P17 is 17m pitch and C28 is the 28m rope needed for it. . . . . . .but what about the bit in between ?
Any help greatly appreciated.  Thanks.  KP

B = broche this is permanent bolting

Could the two signs >> mean a Main courante? I ve never seen it either.

Can you perhaps post a scan of the survey?

Did a small search and came up with this document

And some other survey examples of the same area

P    Pitch
[ ]    Operational rigging
CP    Corde precedente (previous rope)
E    Escalade (free climb)
1AN    1 Natural anchor
1AN Arbre    (ditto/tree)
1S    1 Spit
1S(!)    1 spit requiring backup/danger
2S en Y    Two spit y-hang
1AN+1S en Y    Equalised y-hang on 1 natural anchor and 1 spit (spit = SDA self drilling anchor)
1P    = Piton
1G8    8mm expansion bolt
1B    eyebolt
1S(frac)    Rebelay on 1 spit/SDA
1AN(frac)    rebelay on natural anchor
1AN(dev)    deviation on natural anchor
1S(dev)    deviation on 1 spit
->    Horizontal traverse
up arrow = ascent
diagonal up arrow = ascending traverse
diagonal down = work it out
down arrow = er,.... guess
Arrows usually have a length next to them in metres

Hello to contributors 'Leclused' and 'Cap'n chris',

Thanks to 'Leclused' for the references which provided a definitive "Fiche d'equipment" for the Biefs Bousset and to 'Cap'n Chris' for the equally definitive French Rigging Glossary from Marbach's APT.

Feeling a lot more confident now !

Thanks and regards,

Keith P

We've just come back from the vercors and found that in some places, where the rigging guide indicates a deviation, there were narrow holes drilled through the rock. These were too small diameter to thread a sling through or even a 9mm rope, so we had to buy some dyneema to use.

Some other rigging thingy:

Sometimes you can see a recommandation to use an "AS" in a spit. This is an ammarge souple.
