Fria Mountains

The Sierra Fría rises above the drier plains of central Mexico. Running roughly north to south, this mountain country divides the upper waters of the Juchipila to the west from those of the Río Verde to the east. Forests occupy its cooler heights, while ravines descend towards the surrounding valleys. Springs in the canyons and moisture carried into the western slopes sustain vegetation distinct from the semi-arid uplands beyond.
