Follow Australian Olympic snowboarder Torah Bright as she heads from her home in the foothills of the Australian Alps, deep into Alaska's glaciated Chugach mountain range. Torah dedicated her life to conquering the mountain, and now she's working with her team to understand and protect these epic ecosystems from an ever-changing world. Standing over the ledge of a 2000-foot vertical drop, we unravel the science behind the earth's most incredible mountain environments and ride these untamed peaks.
