The peace and quiet that envelope a lone hiker on a leaf-riddled trail or a rock climber perched on the top of a cliff seem a world away from the noise of a social media feed. But Department of Mechanical Engineering (MechE) alumnus Jim Christian SM ’14 had an idea to tap into the superabundance of social-media data to benefit athletes and outdoor adventurers. He, along with MIT Sloan School of Management alumnus Brint Markle MBA ’14, created a device that could help determine avalanche risk. Their device has led to a network in which people can upload and share critical real-time information about the conditions—including avalanche risk—on a particular slope or mountain.
