Mount Whitney is the tallest peak in the lower 48 states. But at over 14,000 feet, hiking the mountain is anything but routine, especially in early summer. In a new piece on the website Outdoor Online, journalist Megan Michelson writes about her own close call on the mountain thanks to climbers who were unprepared. She also talks about a growing culture of selfie-induced "summit fever" which she says is making it unsafe for others on the mountain. She joined us on Valley Edition to talk about what's wrong, and how to change it.
