A giant among geologists breaks new ground.

Ursula Marvin (1921-2018) was an intrepid adventurer from the start. A Vermonter by birth, she skied over icy potato fields and marveled at the moonlit mountains beyond, positive her future held something far more exciting than the humdrum tedium of scientific inquiry. But by the time she entered college, the field of planetary geology had captivated Marvin, and she was entranced by the information that rare earth minerals and moon rocks could communicate. Her curiosity about these other worlds brought Marvin to the ends of ours. Sharp, capable, and undeterred by the sexist stumbling blocks meant to thwart her, Marvin became the first female scientist to hunt the harsh landscape of Antarctica for meteorites, chasing the adventure she’d hungered for since childhood. But achievement at such scale is rarely won without adversity, and this feat was no different. Hampered by environmental challenges and plagued by self-doubt, Marvin nevertheless stayed the course, eventually becoming the preeminent expert on the first meteorite discovered on Earth and, ultimately, the much-deserving namesake of geological wonders earthside and beyond. Wallace’s text uses technical terms in context and renders the less glamorous labor that makes thrilling scientific discovery possible. Charming details peppered throughout add a personal texture to Marvin’s impressive figure. Carpenter delivers stunning visuals to match, her two-page spread capturing the glow of the midnight sun especially enchanting.

A luminous tribute befitting a brilliant trailblazer.
