In addition to chronicling her own encounters with the people and the place, Wheeler brings the past alive as well, through vivid stories about the heroes of polar exploration: Shackleton, Scott, Amundsen, and others who practically become secondary characters in Wheeler's account. But it is her interactions with the living people who make up the community--scientists, drifters, and dreamers who have settled this forbidding landscape--that make Terra Incognita a rare and worthy book.
