When a hiker goes missing, the public often pictures helicopters and grid searches. Former National Park Service protection ranger and author Andrea Lankford says the reality is more complicated and more human: one-person patrols hours from backup, perishable rope and medical skills, families living in limbo, and a growing ecosystem of online sleuths and volunteer searchers who sometimes find what agencies miss.

In this episode of Policing Matters, host Jim Dudley speaks with Lankford about what “the thin green line” looks like in practice and what her investigation into three Pacific Crest Trail disappearances taught her about technology, teamwork and trust.

About our guest

Andrea Lankford is a former National Park Service ranger who performed firefighting, law enforcement and life-saving wilderness medicine in some of the nation’s most demanding parks, including Cape Hatteras, Yosemite and the Grand Canyon. She received multiple awards for her work as a ranger investigator and implemented the “Heat kills, hike smart” public education program, which has been credited with preventing heat-related deaths at the Grand Canyon and continues to save lives today.

Lankford is the author of five nonfiction books, including “Ranger Confidential: Living, Working and Dying in the National Parks” and “Haunted Hikes: Spine-Tingling Tales and Trails from North America’s National Parks.” Her most recent book, “Trail of the Lost: The Relentless Search to Bring Home the Missing Hikers of the Pacific Crest Trail,” was an instant New York Times bestseller.
