Wolf, the highest volcano of the Galápagos Islands, is located near the equator at the N end of the archipelago's largest island, Isabela. The summit caldera is 5.5 x 7 km and 600 m deep, with recent lava flows covering the broad caldera floor. Prominent unvegetated lava flows are visible on the flanks to the sea. Wolf's 1797 eruption was the first documented in the Galápagos Islands.
