Input: Question: What is the peak elevation of the mountain range that Poxte is part of? Passage:Poxte is a river and valley of the Maya Mountains in Guatemala. The valley is noted for numerous Maya sites such as Ixtutz and the Petén Caves. The river is located on the southwest of the Dolores plateau and northwest of Poptún, in the Guatemalan department of Petén. The source of the river is on the same plateau, near the villages of Boca del Monte and Santo Domingo. The river flows westwards through the hamlet of Poxte, it then disappears amongst the karst topography and resumes its course to the west. It continues westwards into the San Juan River, which is a tributary of the Machaquila River. The Machaquila River feeds into the Pasión River, which flows into the Usumacinta River and into the Gulf of Mexico. The upper reaches of the Poxte River shares its drainage with the Mopan River, which flows eastwards into the Caribbean Sea.
