Samalayuca Dunes

The Samalayuca Dune Fields, more traditionally known as Los Medanos (the dunes), or more recently referenced as Medanos de Samalayuca are a series of large but separated fields of sand dunes located in the northern part of the Mexican state of Chihuahua. The dune fields are scattered over a wide expanse of desert to the south, southwest and southeast of Ciudad Juarez. The dune fields are located in a 2000 km2 area known as the Samalayuca Desert.

The Samalayuca Desert and its dune fields are part of the much larger Chihuahua Desert region.

The best known portion of the Samalayuca Dune Fields lie in and around the village of Samalayuca. These dune fields are the most noticeable because they lie across the much traveled north-south route between Chihuahua City and El Paso del North. This portion of the dunes is also the most dramatic, having high dune profiles shaped by the wind in the lee of Cerro de Samalayuca.

The dunes are composed of almost pure quartz (SiO2). They are white or tan in appearance. They are fine and move with the wind. The wind has formed the dunes by carrying sand until it became deposited and concentrated in natural land depressions. The action of the wind continues to constantly reshape the dunes. Some of the dunes near Samalayuca are tall and dramatically shaped and marked by the wind.

For centuries the sands of these dune fields were historically significant because they lay across the much traveled north-south route between Chihuahua City and "The Pass of the North" at the site of the border cities of Ciudad Juárez and El Paso. Before the era of the modern highway and the railroad, travel by foot, horse or oxen across this extended barrier of some 30 kilometers of loose sand was laborious and dangerous, but travelers had the option of a longer (and thus more time consuming) detour around the east side of the dune fields.

Today the dune fields are becoming known for their tourist and recreational potential, and as a habitat for the many unique endemic species of plants and animals living in a rare ecosystem in the Samalayuca desert. The high silica content of the sands has also attracted industrial interest.
