There is a sanctuary found atop Mount Tlaloc, dedicated to the god, Tlaloc; it is thought that the location of this sanctuary in relation to other temples surrounding it may have been a way for the Aztecs to mark the time of year and keep track of important ceremonial dates. Research has shown that different orientations linked to Mount Tlaloc revealed a grouping of dates at the end of April and beginning of May associated with certain astronomical and meteorological events. Archaeological, ethnohistoric, and ethnographic data indicate that these phenomena coincide with the sowing of maize in dry lands associated with agricultural sites. The precinct on the summit of the mountain contains 5 stones which are thought to represent Tlaloc and his four Tlaloque, who are responsible for providing rain for the land. It also features a structure that housed a statue of Tlaloc in addition to idols of many different religious regions, such as the other sacred mountains.
