Altiplano (Central Plateau) is in San Luis Potosí. The Altiplano is a high desert with high mountain ranges and a moderate climate although it can have snowstorms in the winter. It boasts some of the most diverse varieties of cacti found anywhere.
The advent of the railroad extended advancement from the capital of the state to the other parts of the Altiplano.
The native Guachichiles occupied the largest territory of the Chichimecas (a generic term for less civilized tribes of the north) but have been greatly impacted by development of the region. The Huichol are thought to have come from San Luis Potosí and engage in an annual migration to Real de Catorce.
Although plateau or altiplano might indicate that this region is flat, it is far from it. High mountain ranges are found throughout the Altiplano and many of the towns are located adjacent to them.
