Cloudwalker, the 1985 Banff Mountain Film Festival award-winning mountaineering film, follows Mark Wilford and Jeff Lowe as they prepare to climb a new route on this wild and majestic spire of the Alaska Range's Bear's Tooth South Summit (the south summit of the Mose's Tooth Massif). Featuring inspiring footage of the two climbers at the top of their game honing their mental and physical abilities to prepare for this challenge, then climbing the classic Naked Edge route in Eldorado Canyon, and interviews revealing the inspiring philosophies of two of America's most prolific and talented climbers, Cloudwalker helps preserve and celebrate the culture and heritage of climbing.
