This rock climber sure knows what she's doing because Sasha DiGiulian is a world champion climber. She is the first North American woman to climb the grade 9a, 5.14d, widely known as one of the most difficult climbs to be achieved by a female. You might recognize her because we first Skyped with Sasha in 2013 when she accomplished this climb. Now we see her summiting Lost Pencil in Joshua Tree National Park, California. We are impressed, girl!
