Two female botanists – Elzada Clover and Louis Jotter – made headlines for riding the rapids of the Colorado River in 1938 in an effort to document the Grand Canyon’s plant life. In Brave the Wild River: The Untold Story of Two Women Who Mapped the Botany of the Grand Canyon, author Melissa L. Sevigny retraces their journey and shows how the ambitious river expedition, one that many believed impossible for women, changed not only Clover and Jotter but also our understanding of botany in this remote corner of the American West.
