Cerro del Muerto, Mountain formation in Aguascalientes, Mexico

Cerro del Muerto is a mountain within the Sierra del Laurel range that rises to 2,440 meters and dominates the landscape of Aguascalientes. Its slopes are covered with oak forests and thorny scrubland that shape the terrain's appearance.

On 26 May 2008 the Government of Aguascalientes decreed Cerro del Muerto a protected natural area under the category of Monumento Natural, citing its landscape and habitats. Conservation work since then has included a visitor centre, a surveillance post and forest guards patrolling the El Picacho area. The land remains private and ejidal property.

The mountain's shape resembles a person lying down, which is why local people call it Cerro del Muerto, meaning Hill of the Dead. This visual impression remains central to how residents relate to and think about the place.

The main access is El Picacho, also called Los Pies del Muerto, on the south side of Federal Highway 70 about 10 km from Aguascalientes toward Calvillo; a trail from there leads to the summit. The mountain can also be reached via the link road between highways 70 and 45, or from Los Caños on the Villa Hidalgo road. Slopes reach 58 degrees of incline.

The protected area covers 5,862.034 hectares, about 1.03% of Aguascalientes state territory, and lies between 1,842 and 2,440 meters. Its name comes from the silhouette of a reclining person: the "head" points southwest and the "feet", called El Picacho, southeast. The oldest rocks in the state, Jurassic schists, crop out in a small northern portion.
