Today Jack shares the newly available video of Christian Core on his boulder problem Gioia 8C+ at Varazze, taken from the documentary i Core, my climbing family by Angelo Poli. https://vimeo.com/71151970 There's also an excellent safety post from Climbing Magazine, see below: http://www.climbing.com/blog/know-the-ropes-prevent-lowering-accidents/ Over the past decade, nearly 80 lowering incidents, including fatalities, have been reported in Accidents in North American Mountaineering, the AAC's annual compendium of climbing accidents. And unlike many climbing disasters, nearly every lowering accident is 100 percent preventable—nearly all are the result of simple climber errors. The 11-page article describes essential ways to prevent all-too-common lowering accidents stemming from miscommunication, belay errors, and poor judgment.
