The East Madre Mountains stretch high and extend north and south, dividing the Tlaxcala Highland from the Totonac Lowland. At the southeastern point where the mountains meet, there stands a towering peak rising into the clouds, North America's third highest peak, Citlaltépetl, the Divine Mountain. In the Navajo language, "citlal" means "star," while "tepētl" means mountain. Thus, this 5,600-meter-high mountain is also referred to by the local mountain tribes as "Star Mountain."
"Star Mountain" stands tall, with the mountain range extending. The long earthen Great River originates at the foot of Star Mountain, meandering eastward, flowing through Earth River City, Feather Bird City, and after traveling over 700 li, finally reaches the river bend village only 20 li from the estuary.
