Andrew Lock and climbing partner, Hector Ponce De Leon of Mexico, have been unable to secure the climbing permit required to climb Shishapangma (8072 m) in Tibet. The expedition was cancelled on April 13th, only days before the new issue of Outdoor Australia magazine hits the stands featuring Andrew's latest climb. Andrew Lock has made four previous attempts on the mountain, the last in 2007. This is the final of the world 14 summits over 8000 m for Andrew, making him the first Australian and only the 15th climber in the world to successfully complete this feat. Andrew hopes to return to Tibet after the monsoonal rains to make another attempt. You can check out the details of the expedition here.
