We traveled to Arizona to meet 21-year-old Sierra Blair-Coyle who told us about her love for climbing and how she returned to the sport after a back injury that almost ended her career. Then we joined her on a deep water solo—free climbing on cliffs over water. Check out Sierra's climb in 360˚! bit.ly/1jBjc5y The 360˚ experience can be viewed in Chrome or Firefox.
