Skander Spies, a volunteer with Denali National Park's climbing rangers, had just headed out on patrol on the Kahiltna Glacier. Although they didn't know it yet, the rangers would record eleven separate crevasse falls that day, including Skander's. And his incident was scarier than most!

In this story from the mountains near Steamboat Springs, Colorado, a nighttime search for two lost skiers takes a dramatic turn when one of the rescuers is caught in an avalanche.

On November 12, David had just finished a two-pitch climb outside of Joshua Tree National Park in California. From the top, he lowered his partner to a big ledge so she could walk off. He then decided to down climb to the ledge without a belay. In this episode, David describes the accident that followed with remarkable self-awareness and good humor.

Around sunset on November 7, 2015, Angela Uys (26) was at an anchor partway up Snake Dike on Half Dome, preparing to rappel. Her tether system was not effectively clipped to the anchor, and when she weighted the system it failed. She fell approximately 500 feet to her death. In this episode, Ashley speaks with Yosemite climbing ranger Jesse McGahey, who responded to and investigated this tragedy, and the two discuss what went wrong and how similar accidents might be prevented. You can read Jesse's full report from Accidents in North American Climbing here: http://bit.ly/2gbz1Ba.

Climber and backcountry skier Steven Lozano summited Mount St. Helens with a friend on a beautiful April day. When two climbers joined them on top, one of them, who was making his 69th ascent of the mountain, asked Steven to take a photo of him with Mt. Rainier in the background. What happened next will be seared into Lozano's memory forever.

Felipe Proaño, a North Face sponsored climber and native of Ecuador, took a long fall off Black Elk, a classic 5.11 climb in Wyoming's Wind River Range, and nearly left a finger behind. Felipe tells Ashley how his desire to be a "badass" backfired, with painful results.
