Laguna de Ayarza (pronounced as /es/) is a crater lake in Guatemala. The lake is a caldera that was created some 20,000 years ago by a catastrophic eruption that destroyed a twinned volcano and blanketed the entire region with a layer of pumice.[1] The lake has a surface area of 14 km² and a maximum depth of 230 m.[2] The lake has a surface elevation of 1409 m.[3]
