An avalanche occured while we were praticing advanced winter climbing techniques at Hasandar valley (Iran). Just after a few minutes another avalanche occured which is much more bigger and destroyer than the first one.although it was slow but we still lost one of our tents (we saved 2 others). this is a video about this avalanche.

2nd Avalanche just after the 1st one that took our tent (you see me in black with my camera):
The 2nd Avalanche from my view point.
"How do you distinguish between being off-route and putting up a first ascent?"
