Christine Boskoff was a mountaineer who pushed boundaries and set records.

She climbed mountains no North American woman had ever summited, and she was the only American woman to have reached the top of six of the world’s 8,000-meter peaks. She was also a well-respected guide.

But despite her impressive resume, Chris’s story went largely untold — until this year.

This spring, writer Johanna Garton published a book called Edge of the Map, chronicling Chris’s rise in the mountaineering world. Johanna joins us to talk about how Chris got her start, the challenges she faced as a woman in a man’s realm, and the complicated moral questions surrounding her death on a sacred mountain.

When David Klebosky was out in the desert earlier this year, he ended up being shot at. The gunfire wasn’t malicious, but there were bullets coming at him.

Yet David didn’t freak out.

This kind of response is typical for David; he always seems to remain calm in the face of stress.

On this episode, producer Max Wasserman delves into David’s past and explores what makes some of us so unflappable.
