Un/Mapped: A salute to inspiring female explorers—past and present

Trekking solo across a frozen tundra, walking untethered on the ocean floor, circumnavigating the globe: women explorers have done it all, and much more.               After 30 remarkable years in Galápagos, our legendary expedition leader hangs up her walkie-talkie. Find out what she'll miss—and what she looks forward to (Hint: it involves zebras.)               National Geographic photographer Susan Seubert has traveled the world, camera in hand. See her favorite images—and her thoughts behind them.     © 2019 Lindblad Expeditions - National Geographic   032719_ENEWS_TA
