In the summer of 1938, two botanists took a trip down the Colorado River. They wanted to catalog cactuses in and around the Grand Canyon.
Now, a new book details their trek, based in part on letters and diary entries made by the two women, as well as others on the expedition.
Melissa Sevigny is a science reporter at KNAU in Flagstaff; her book is called “Brave the Wild River.” She joined The Show to talk about it.
