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).

The elongated island of Pinta is the northernmost of the active Galápagos volcanoes. This view from the summit of Pinta looks down on pyroclastic cones and lava flows on the southern flank of the shield volcano. Numerous young cones and lava flows originated from NNW-trending fissures cutting the island. 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. The island in the distance is Marchena volcano.
