looking through this thread brought back some memories!I spent 7 weeks trekking in the solo khumbu in 1995,towards the end of the trip we were in the gokyo valley when it started to snow,after a day or so the snow must have been 5 feet deep,the next village down from us was wiped out by an avalanche-https://en.wikipedia.org/wiki/1995_India_cyclone-there was no way out for us as it was too dangerous due to further avalanche risk,after a few days a helicopter came to check out the situation and they day after they started airlifting us all out.there must have been 150 locals and tourists so it took several days.It was interesting to see how different people react to situations like that,there was no real danger to our village and there were plenty of supplies available,a kiwi guy organised everyone by number so you had a decent idea of when your evacution on the helicopter was,families,sick first etc but the number of panicked people that ignored this and forced there way onto the first helicopters was surprising.
