SfondoA Quaternary lava-dome complex lies in the center of a semi-arcuate depression of uncertain origin near the city of Totonicapán. A small symmetrical lava dome, Cerro de Oro, is located on the ESE flank of the larger edifice, 3029-m-high Cuxliquel. The headwaters of the Río Samalá trace an arcuate path around the dome complex beginning on its SE side around to the north side and then to the SW. Thick Los Chocoyos pyroclastic-flow deposits from the eruption that formed Atitlán caldera to the SE fill much of the basin and extend down the Río Samalá to the SW.
