Trans-Mexican Volcanic Belt
May 10th - July 31st
The Trans-Volcanic belt, also known as the Sierra Nevada covers central-southern Mexico. Several of its highest peaks have snow all year long, and during clear weather, they are visible to a large percentage of those who live on the many high plateaus from which these volcanoes rise. The mountains are home to the Trans-Mexican Volcanic Belt pine-oak forests, one of the Mesoamerican pine-oak forests sub-ecoregions. The remoteness, relative inaccessibility, and many habitable valleys of the Sierra Madre made it a refuge for a number of indigenous peoples who succeeded in retaining much of their aboriginal culture for two or three centuries after their first contact with the Spaniards. These groups include the Huichol and Cora in the southern states of Nayarit and Jalisco, the Tarahumara (Rarámuri) in the north (Chihuahua), and a number of other groups, especially in the Sierra Madre del Sur.
