The Sonoran Desert is both the setting around Santa Teresa and a force in the novel’s spatial imagination: a broad, exposed landscape crossed by borders, roads, industrial development, and hidden sites of wealth and violence. It connects the city to the United States through formal crossings and commercial traffic, even as its expanses and margins make people and events hard to trace. The desert’s apparent openness therefore coexists with sharply unequal mobility and persistent uncertainty.

Borderland and City

Santa Teresa lies within a rapidly expanding border region. Its industrial parks sit beside scrap-built neighborhoods and vacant ground; highways lead out of the city, while the border fence and Arizona desert mark the northward edge of the landscape. From a hotel terrace, a visitor sees the desert spread south and west, a view that presents grandeur and solitude alongside the city’s unsettled growth.

The border is not a simple division between two self-contained worlds. At the crossing, travelers present passports, vehicle papers, and press identification to separate American and Mexican officials. The physical fence remains visible between the posts, but people and goods move across it continually. Commercial traffic is especially consequential: Pedro Uribe’s more than one hundred cargo trucks carry merchandise from maquiladoras in Hermosillo and Santa Teresa across the border every half hour or hour, linking industrial production to markets and property on both sides.

Industry and Uneven Development

Santa Teresa’s desert setting is transformed by factories, roads, and population growth, but development does not erase the region’s inequalities. Industrial parks appear as islands of light against surrounding scrap-roof settlements; the factories are fenced, while workers arrive and depart by bus. The city’s expansion is described as nearly continuous, extending through poor districts, vacant lots, and industrial zones rather than following a settled boundary.

The contrast between industrial activity and the landscape around it is particularly clear in the account of an evening visit to the Arsenio Farrell industrial park. Its roads converge among fenced factory buildings, and workers’ buses continue their daily routes. Nearby stand roofs of scrap and another industrial park beyond distant dwellings. The scene makes the maquiladora economy visible as part of a larger geography of labor, infrastructure, and deprivation, not as an isolated enclave of prosperity.

Violence, Concealment, and the Desert Interior

The desert also shelters places set apart from ordinary civic life. In an account assembled from investigative reports, the ranch properties of wealthy owners are described as isolated compounds sometimes called narcorranchos. They may remain empty for long stretches, then become active when workers prepare the house and armed guards establish a perimeter before the owners and their associates arrive. The desert’s remoteness makes these properties difficult to observe and allows their activities to sit beyond the routines of the city.

This landscape intersects with the crisis of murdered women in Santa Teresa. The deaths are periodically discussed in public, but attention rises and fades while people return to work; the city’s factories, migration, poverty, and criminal networks form part of the same environment in which the killings continue. The desert does not provide a single explanation for the violence. Rather, its distance, the region’s uneven development, and the interlocking movement of labor, goods, and criminal power give disappearance a setting in which responsibility can remain difficult to establish.

Narrative Significance

The Sonoran Desert joins spaces that might otherwise seem separate: the American border post, Santa Teresa’s expanding neighborhoods, factories, and remote estates. Its openness is not freedom from power. The border controls passage, industrial life organizes movement, and secluded properties can conceal activity; meanwhile, the scale of the landscape makes surveillance and knowledge incomplete.

The desert is therefore more than a backdrop. It gives the novel a geography in which visibility and absence coexist: the fence can be seen, trucks cross regularly, and factories illuminate the night, yet the people most exposed to violence remain vulnerable to neglect and disappearance. The region’s distances and contrasts turn the borderland into an active part of the book’s account of mobility, exploitation, and impunity.
