Scientist Diana Wall is obsessed with worms and other invertebrates that live underneath the soil.
Wall, an ecologist at Colorado State University, has studied these microscopic species in Antartica for 25 years, and says they offer insight into climate change. Now, a valley in Antarctica carries her name.
On Thursday, Wall will be inducted into the Colorado Women's Hall of Fame, along with five other new living members and four new members inducted posthumously.
