Raven Black Pyramid

If you shop for artisanal bottles in Prague, you probably know Honza. He runs a beer shop called Base Camp near Letná, and sometimes he climbs mountains too. This year he is going on K2, alone and without oxygen. The Black Pyramid is a rock formation towering over the camp on the second level. This is the most technical part of climbing, where climbers use fixed ropes to tackle both rocky and icy passages.
