Rincón de Parangueo, located in the Santiago Valley, in the State of Guanajuato is a maar that has dried due to the large groundwater ex­traction required for irrigating crops in the region. The active deformation of the maar’s bottom (which includes both uplift and subsidence) has created a series of structures on its surface. Photo: Jaime J. Carrera-Hernández.
