This week’s infographic comes to us from Petzl, specifically a scan out of their Mountaineering axes manual that came along with my Petzl Snowalker 60 cm ice axe. Not the best scan, but, I loved it and wanted to share it. Unfortunately I could not find a PDF copy of it on their site…

It will always be exciting to read articles from other authors and use a little something from
other sites.
