Neighbouring volcanic centres to Wheelwright include Ojos del Salado farther south. The caldera is set into a terrain formed by volcanic rocks of Miocene-Pliocene age, chiefly lava flows of andesitic-dacitic composition. Together with the neighbouring Laguna Amarga caldera and Laguna Escondida caldera Wheelwright forms an alignment of Miocene-Pliocene calderas; the latter caldera in part overlaps with the Wheelwright caldera.
