Dead Sea Sea is an endorheic lake located in the Jordan Rift Valley, a geographic feature formed by the Dead Sea Transform (DST). This left lateral-moving transform fault lies along the tectonic plate boundary between the African Plate and the Arabian Plate. It runs between the East Anatolian Fault zone in Turkey and the northern end of the Red Sea Rift offshore of the southern tip of Sinai. It is here that the Upper Jordan River/Sea of Galilee/Lower Jordan River water system comes to an end. The Jordan River is the only major water source flowing into the Dead Sea, although there
Poxte River 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. The Poxte River Basin itself measures long and is wide. The river valley drainage is broken and confused, and the land has been largely cleared of forest in order to graze cattle. The Poxte valley includes modern settlements of Las Nuevas Delicias, La Lucha, Santo Domingo and Boca del Monte.
