The rocks from the Taos Plateau volcanic field in Air are filled with holes from the air bubbles trapped when the lava solidified upon cooling. The sand is a mixture of tan-colored quartz-filled sand from Lake Michigan and black magnetite-rich sand not typically found in the lake but emerges after a storm. The subtitle, "Storytellers," alludes to the basalt holes holding stories of their journey through geologic time—”what they witnessed during the passage from beneath the Earth’s surface to the place where I found them.” The clay cartouche bears a drawing of the night constellation she saw from the Taos Plateau.

"Air, Line, Color" is inspired by jewelry with the same title made by multidisciplinary artist, Stephanie Simek, whose necklace of semiprecious stones was akin to a talisman Bello brings with her to all her artist residencies throughout the U.S.
