From one of the worldâs most renowned cave divers, a firsthand account of exploring the earthâs final frontier: the hidden depths of our oceans and the sunken caves inside our planet
More people have died exploring underwater caves than climbing Mount Everest, and we know more about deep space than we do about the depths of our oceans. From one of the top cave divers working todayâand one of the very few women in her fieldâInto the Planet blends science, adventure, and memoir to bring readers face-to-face with the terror and beauty of earthâs remaining unknowns and the extremes of human capability.
Jill Heinerthâthe first person in history to dive deep into an Antarctic iceberg and leader of a team that discovered the ancient watery remains of Mayan civilizationsâhas descended farther into the inner depths of our planet than any other woman. She takes us into the harrowing split-second decisions that determine whether a diver makes it back to safety, the prejudices that prevent women from pursuing careers underwater, and her endeavor to recover a fallen friendâs body from the confines of a cave. But thereâs beauty beyond the danger of diving, and while Heinerth swims beneath our feet in the lifeblood of our planet, she works with biologists discovering new species, physicists tracking climate change, and hydrogeologists examining our finite freshwater reserves.
Written with hair-raising intensity, Into the Planet is the first book to deliver an intimate account of cave diving, transporting readers deep into inner space, where fear must be reconciled and a missionâs success balances between knowing oneâs limits and pushing the envelope of human endurance.
