Big Drum Anchors – photo by Ofelia Huang

Ofelia Huang reports that on Friday July 24th, the anchors of popular sport climb #369 Big Drum in Music Hall failed while a climber was lowering off them to the ground. The anchors failed when the climber was around 4m from the ground. The climber sustained minor injuries but is reported to be fine.

The type of bolts used are Petzl Collinox bolts made of 316L stainless steel, making this the first failure of a 316 “Marine grade” stainless steel bolt at Long Dong.

Update (August 26, 2015): It has been confirmed by Petzl America that the bolts in the photo and in this incident were actually 304 grade stainless steel.

The surrounding climbs #367 Fucking Fall and #370 Finger Crack , Musical Arete and 383 Wedding Route use the same Petzl Collinox bolts and we recommend climbers to avoid all of these popular climbs at this point until the routes are rebolted.
