Lake Atitlan sits within the Sierra Madre mountain chain which represents the physical divide between the Guatemalan highlands and the Pacific lowlands. It was thus ideally situated to act as a hub for cultural and economic exchanges between these two contrasting ecological zones. The three imposing volcanoes that line its southern shore, however, severely limited options for travel between these areas and commerce and settlement thus concentrated around obvious natural corridors such as those...
A Record of Late Holocene Volcanic Activity from Highland Guatemala (2015)
A record of late Holocene volcanic activity in highland Guatemala was inferred from sediment and tephra stratigraphy in two cores from Lake Amatitlan. Electron microprobe analysis of glass from the tephra samples suggests most eruption deposits are of local origin, coming from nearby Volcanoes Pacaya and Fuego. The 6th-century Ilopango ash is clearly visible, and a few tephra samples have not been correlated to particular volcanoes or eruption events. Using dates from this sequence with others...
