Rising 14,000 feet above sea level, Mount Rainier is where many aspiring mountaineers go to test their skills. Crevasses, hanging glaciers, weather that's not always predictable.

There was a lot of fear but no understanding." After years spent honing skills in the mountains, Greg views Rainier as a mountain of potential. Now, he's set his sights on two routes in two days.
