awesome, truely good stuff.
i was messing about on BP a few years back in summer of course, and recall digging out lengths of 5mm fixed line lower down that took half the season to expose and were still under 2m of snow in most places.
made me contemplate the sheer mentality of guys being out there in winter.
same season denis ubroko was out there caching their stuff for the following winter - just seeing their rack of mattocks for smashing ice to melt water put it into perspective.
wild stuff.
