Katherine Etchison and Sue Cameron exist an abandoned, North Carolina mine.
N.C. Wildlife Resources Commission biologist Katherine Etchison (L) and Service biologist Sue Cameron exit an abandoned North Carolina iron mine after surveying a section of it for bats. The mine is so expansive, biologists divide into teams in order to visit the entirety of the mine in a single day. As Etchison and Cameron surveyed one portion of the mine, another two-person team worked a separate portion.
