A cenote (English pronunciation: /sɨˈnoʊtiː/ or /sɛˈnoʊteɪ/; Spanish: [seˈnote]; plural: cenotes; from Yucatec Maya dzonot or ts'onot,[1] meaning "well"[2]) is a sinkhole with exposed rocky edges containing groundwater. It is typically found in the Yucatán Peninsula and some nearby Caribbean islands. The term is derived from a word used by the low-land Yucatec Maya to refer to any location where groundwater is accessible. Source
