Santa Cruz
"The highlands of the broad Santa Cruz shield volcano rise to the north above the renowned Charles Darwin Research Station at Academy Bay. The oval-shaped, 32 x 40 km wide island is capped by youthful pit craters and cinder cones with well-preserved craters that largely bury a shallow summit caldera. Older uplifted submarine lava flows are found on the NE part of the island and at the fault-delimited offshore island of Baltra. The highland scoria cones are grouped along an E-W belt parallel to recent fault scarps that border Academy Bay. The youngest lava flows were erupted from vents along the summit fissure and on the northern flank. Their fresh morphology and sparsely vegetated surfaces suggest they may be only a few thousand years old, although their ages are not known precisely."  -Smithsonian Volcano Archive
