San Cristobal
About San Cristobal
San Cristóbal Island consists of a densely vegetated western part and a lower, younger eastern part with many unvegetated lava flows. The morphology on the SW side of the resembles low-angle Hawaiian shields more than the steep-sided shields of Fernandina and Isabela Island. Most lava flows on the NE part of the island originated from SW-NE-trending fissures. Some of the flows have reached the sea, where littoral cones formed. The dates of the latest eruptions are unknown, but possibly less than 1,000 years old. Kicker Rock, two small islands about 5 km off the NW coast, is an eroded remnant of a tuff cone.
