This mural, entitled A Vortex of Time and Space, is part of the airport’s unique collection of artist-created murals that greet visitors coming and going at the north and south curbs of Terminal Four. Chabot worked with fourth and sixth grade students at Wilson Elementary School – not far from Phoenix Sky Harbor Airport in Phoenix – to create shapes and images that the artist pressed into a mold and then inlaid into the surface of each ceramic tile. She considers the students’ additions to the tiles “memory fossils.” Each tile surface looks like a slice of earth uncovered during an archaeological excavation.
