The Sierra de Morones extends north and south through the state of Zacatecas.

The Juchipila River drains the eastern slopes of the Sierra, running southwards to empty into the Río Grande de Santiago.

The Bolaños River, another tributary of the Río Grande de Santiago, drains the western slope of the Sierra.

The Río Grande de Santiago bounds the range on the south and southeast.
