| The Sierra de Los Tuxtlas is the insular volcanic mountain range centered on Catemaco, bordering on the Gulf of Mexico in south central Veracruz, Mexico. The Sierra encompasses the gulf coast, slopes and foothills of the volcanoes, extending inland from near Angel R. Cabada to the northeast, to southwest of Acayucan and east to near Laguna del Ostion. The two major Sierra components are the Volcano San Martin Tuxtla complex to the northwest and the Sierra Santa Marta to the southeast. The southern Sierra apparently formed 5 to 7 million years ago, while the northern portion began to form 2 to 3 million years ago. Hundreds of volcanoes and cinder cones dot the area with a handful reaching above 5000 feet. Lying on a NE - SE axis the Sierra is app. 75 miles long and 44 miles at its widest. All the coastal area and most elevations above about 1000 feet are included in the Los Tuxtlas Biosphere Reserve The Gulf of Mexico bathes the shores of the Sierra from Angel R. Cabada to Pajapan. Most of the population centers are inland. Inhabitants are almost 100% mestizos in the northern section, while the southern section has large percentages of Popoluca and Nahua speakers. |
