The city of San Francisco de Macorís is located in the North Region of the Dominican Republic (Cibao Region) between the Septentrional Mountain Range at the north and the Cibao Valley at the southern part. San Francisco de Macorís has hills to the north which provide a great view of the city during evening hours. The Jaya River is prominent on the western part of town.
Districts The city has the following subdivisions:
Relief The relief of Duarte Province ranges from above sea level, reaching its highest elevation at "Loma Quita Espuela". This name allegedly comes from the time when the Spaniards were exploring the island, since the hill was too steep to ride their horses, they had to dismount and remove their spurs and undertake the ascent on foot. There are two main geologic regions: the north slope of the Cordillera Septentrional and the rough topography of the Delta del Yuna. On the southern slope of the Cibao Valley in the Yuna Subregion (Easter Cibao), we will find alluvial fans, in combination with deposit hollows, hill areas and platforms, and also alluvial soils into the channels of the flows of the rivers Camú and Yuna. Two faults go through the Duarte Province from east to west. This tectonic deformations are the Septentrional fault, that touches the towns of Arenoso, Castillo and San Francisco de Macorís and the Cibao fault passing through the towns of Las Guaranas, Castillo, Villa Riva Pimentel. The Septentrional fault is located in the northern part of the province while the Cibao fault is located in the southern part of it.
Geomorphology The Yuna River Delta is part of the Cibao Valley, and most of these areas are located a few metres
above sea level and therefore wetlands abound. Its main rivers are the Great Yuna and Caño Estero, which are the natural drainage of these lands in the province of Maria Trinidad Sanchez. The area consists mainly of swamps with silt and clay, and also large areas of peat deposits. By the rivers are alluvial deposits. The Eastern Cibao Valley (also part of the Cibao Valle) is divided into the provinces of Santiago, Espaillat, Sánchez Ramírez, Sánchez and Duarte, the latter having a higher percentage (about 50%). All cities in this province are rooted in this valley except the city of Arenoso. The floodplains of the Yuna River system occupy a narrow strip on the south side of the valley and there is also a narrow chain of hills, probably middle Miocene limestones, adjacent to the north mountain range. For this province the valley also has marine lacustrine deposits of clay, basically of two kinds: a limestone and other non-calcareous. The Haitises consist of a karst platform, which is composed of hard limestone from the Oligocene-Miocene. The highest elevations are generally tall. The Payabo River crosses the region by a narrow channel filled with alluvial deposits. The Northern Range is a mountain range of sedimentary rocks and highly faulted and folded fobáceas. In this province the Northern Range reaches heights of (Quita Espuela); near San Francisco de Macorís the ridge height is slightly below . It presents some mudstone, limestone and Miocene and Eocene oligocénicos. To the south of Gaspar Hernandez and reaching the Nagua River there is a very complex area with rugged hills of limestone, and tuff, probably with other volcanic and metamorphic rocks, mainly of Upper Cretaceous.
Hydrography There are many rivers and streams in the Duarte Province, the most important ones being the
Camú River, the
Yuna River and their tributaries (Jaya, Cuaba, Nigua, Payabo, among others). The Yuna River and Camú River constitute important sources of water, both for drinking and for irrigation.
Physiography and environment Environmental pollution in Duarte Province is the product of several elements, such as the poor state of latrines, untreated sewage, overflow of streams, indiscriminate use of agrochemicals, backwaters and installation of pigsties on the banks of rivers, and waste from some factories in the province that is thrown into rivers. Soil erosion from deforestation also affects the environment of the Duarte Province. Similarly, the smoke from factories and from burning trash, specifically in the municipality of San Francisco de Macorís, is affecting its inhabitants.
Climate Temperatures fluctuate between , with cooler temperatures affected by rainfall. It is largely an isolated paradise since much of the territory is unaffected by hurricanes or extremely hot weather. Occasional floods can occur due to a rainy season which manifests itself mostly during the month of May. ==Places of interest==
