cerro de trincheras
SEH-roh deh trin-CHEH-rahs
A terraced hill — an isolated, often volcanic hill whose slopes have been shaped with stone retaining walls and platforms by pre-Hispanic peoples of the Sonoran Desert and northwest Mexico. The terraces served as house platforms, garden plots, water-catchment surfaces, and possibly defensive positions. Hundreds of these sites exist from Durango to southern Arizona, some over 3,000 years old, representing one of the longest-lived architectural traditions in North America.
Etymology
Spanish — cerro (hill) + trincheras (terraces, trenches, or entrenchments). The individual terraces are trincheras; the entire terraced hill is a cerro de trincheras. Early Spanish observers interpreted them as fortifications, but the reality is more complex — they are communities built into hillsides, with domestic, agricultural, and ceremonial functions layered together.
Notes
The largest, Cerro de Trincheras in Sonora, has over 900 terraces and is visible across the flat desert from 25 miles away. Tumamoc Hill in Tucson is another.
