In today's episode of Backpacker Radio presented by The Trek, and brought to you by Topo Athletic, we're joined by Mary "Fireweed" Kwart. Fireweed is a thru-hiker, a Deadhead, and a pioneering figure in wildland firefighting with a career spanning more than 30 years. We dive into the challenges of being one of the first women to join the elite Arrowhead Interagency Hotshots, the culture shock of entering a male-dominated field, and some of the most memorable stories from her decades on the fire line. 

Fireweed also reflects on how long-distance hiking has evolved since the 1970s, her tradition of tackling a new long trail every year since retiring, and her deep love and advocacy for California's Bigfoot Trail.

We wrap the show with the best backpacking trails in the Midwest, the thru-hiking advice we wish we'd never given, a debate over whether robotic legs should count as mechanical transport under the Wilderness Act, and the Triple Crown of parts of society we'd turn the clock back for.
