"In her fascinating travel memoir, Winslow offers a compelling glimpse into her misadventures as an inexperienced geologist as she begins pioneering field research in southern South America. Beginning in the mid-1970s, Winslow details her unforgettable experiences that include clinging to a ledge alone as the tide rises over her boot tops, facing near-death experiences with killer whales, and encountering an antediluvian creature with a cavernous mouth and yellow teeth-all while tracing her evolution from an ill-prepared beginner to a competent leader. Over My Head captures one woman's historic journeys into uncharted fjords and trackless forests as she attempts to navigate through the almost exclusively male world of field geology and discovers she must learn to rely on her own inner compass in order to survive."--Amazon.com.
