Lost: Petzl Volta rope in chute south of Mt Winchell

I had to abandon my orange 30m Petzl Volta rope in the chute just south of Mt Winchell, before you get to Thunderbolt pass. I did a full length rap and my rope retrieval system failed thanks to a misplaced stopper knot. The excess rope is tied up tightly and thrown over the big chockstone in the chute to discourage anyone from thinking it's a fixed line. Low chance of getting it back, but if anyone happens upon it please let me know.

Cheers,

Famo
