 The subsidiary site of La Trinidad de Nosotros, located on the shore of Lake Petén Itzá some southeast of the site core, appears to have been an important port for the import and export of goods to and from Motul de San José.Food resources not available in the immediate vicinity of the city were probably provided by the satellite sites dispersed at some distance from the site core, and La Trinidad is likely to have played an important part in supplying exotic goods to the city as well as freshwater foodstuffs such as crocodiles, fish and turtles.Chert nodules were locally available from the first ridges to the north of the lake.
