The deep blue Laguna de Jiloa (left) and the turquoise-colored Laguna Apoyeque dramatically fill two calderas on the Chiltepe Peninsula north of Managua. The 2.8-km-wide Apoyeque caldera, the source of the major Chiltepe Pumice about 2000 years ago, has a more circular outline than the scalloped 2.5 x 3 km wide Jiloa caldera, which was the site of a major explosive eruption about 6500 years ago.
