This Month in Photo of the Day: The Power of Photography

Suspended from an anchor in the rock hundreds of feet above the ice and snow, Mike Libecki hauls himself up a granite tower in Antarctica's remote Queen Maud Land.

See more pictures from the September 2013 feature story "Untamed Antarctica."

Our Your Shot community celebrates the power of photography every day, and we're inviting you to go on assignment to capture change with photo editor Sadie Quarrier and National Geographic photographer Cory Richards.

Before the assignment ends, watch our live Google+ Hangout on October 16 at 1 p.m. EST (5 p.m. UTC) with Sadie and Cory to learn what photography means to them and how you can get involved with Your Shot.
