In early June it was reported that a legally blind mountaineer had successfully climbed Mount Hood. He made it to the top with the help of his faithful guide dog, Rasha, and his best friend, Diego Joven.

Amazingly, John Wimmer, 37, has already conquered about a half dozen mountains across the western United States.

Wimmer has a message to others, he says “Go after your dreams”. He obviously did! He lost his eyesight at the age of 5 but his spirit remained.

Wimmer and friends moved on to tackle Mount Rainier. During their trip they will document the effects of pollution, raise awareness about climate change and raise money for Unicef. You can follow their amazing journey by visiting WhatsYourImpossible.com.
