While most visit the National Zoo for its wonderful array of animals, the Crew spent their morning navigating its grounds using a combination of GPS, laser range finders and topographical maps. Their objective: try to identify trees (without looking at its often conveniently placed species tag), considering its location on the map and approximate height. This outing at the Zoo gave the students an opportunity to learn more about mapping and tree inventory.
