The climate is semi-arid. The highest point is Cerro El Hongo with an elevation of {{convert|1786|m|ft}} at a location of 24° 34′ 20″ North Latitude and 99° 04′ 24″ West Longitude. Most of the San Carlos range is much lower, averaging {{convert|600|m|ft}} to {{convert|800|m|ft}} in elevation.[1] GeographyThe Sierra de San Carlos (Spanish for Saint Charles Mountain Range), southeast of the city of Linares, Mexico is about {{convert|50|mi|km}} east to west and {{convert|20|mi|km}} north to south. It covers a total area of 896 square miles (2,320 km2). The Sierra is located between 24 and 25 north latitude and 98 30 and 99 10 west longitude. Elevation ranges from {{convert|1,000|to|5,859|ft|m}}.[2] Five types of vegetation cover have been identified in the Sierra. Desert thorn shrub (Tamaulipan matorral) is the most common vegetation in northeastern Mexico and covers the driest areas in the Sierra up to 1,600 feet (300 to 500 m) in elevation. A thorn forest mixed with grassland is found at altitudes of {{convert|1,200|to|2,000|ft|m|abbr=off}}. A low deciduous forest averaging about {{convert|25|ft|m}} in height covers the hillsides at elevations of {{convert|1,700|to|3,000|ft|m|abbr=off}}. In the cooler temperatures at the higher altitudes in the Sierra oak-pine forests are characteristic at elevations of more than {{convert|800|m|ft|abbr=off|sp=us}}. About 13 percent of the total area consists of oak and oak-pine forests. A small amount of riparian forest mixed with tall grasses is found along streams and near reservoirs. The riparian forests feature species such as hickory (Carya palmeri) more characteristic of the United States than Mexico. Most of the forests in the Sierra are intact, as they are not of sufficient quality to encourage commercial timber harvesting.[3] No major highways or rivers cross the Sierra, nor are there any large towns or cities. The population is rural or resides in small villages. ClimateThe Sierra de San Carlos has a semi-arid climate with hot summers and mild winters. Precipitation in the Sierra averages about {{convert|28|in|mm}} annually. Most precipitation is in the summer between May and October, although winters are not as dry as in much of Mexico. The climate of the hamlet of San Nicolás is typical of the higher and cooler elevations in the Sierra. {{Weather box|location = San Nicolás, Tamaulipas. 24 41 36N, 98 49 46W.
