Mountaineers Adrian Ballinger and Cory Richards aren't just planning to do the impossible, but they plan on Snapchatting their entire journey – and this isn't the epic duo's first attempt. Last year, these two climbers documented their climb up Everest on Snapchat under the domain #EverestNoFilter, which accumulated thousands of views from people all over. They're not only climbing this beast again, but they're doing it without the use of supplemental oxygen, which they attempted to do the year before. Adrian was close to the summit, but had to turn around after his body went numb. Cory made it to the peak, but as the universe would have it, when he went to pull out his phone at the top, he saw it had run out of battery. Now, this month, these incredible climbers will Snapchat their entire experience once again, only this time they're both making it to the top (and carrying an external phone battery).
