The elongated island of Pinta is the northernmost of the active Galápagos volcanoes. Pinta is a shield volcano with numerous young cones and lava flows originating from NNW-trending fissures. A steep sea cliff truncates the western side of the volcano, which lacks the prominent summit caldera of Fernandina and Isabela Island volcanoes. The fresh, unvegetated lava flows that cover the SE and northern flanks appear to have been erupted during the past few thousand or few hundred years (McBirney and Williams 1969). An eruption of uncertain nature was reported in 1928 (Catalog of Active Volcanoes of the World).
