Ne Theras Mountains

The Ne Theras Mountains are a defining geographical boundary on Anarres, separating its high passes and settlements from the exposed, arid expanses below. They recur at moments of arrival and departure, while their foothills connect the planet’s natural landscape to its port, its settlement history, and the difficult conditions of life there.

Geography and First Impressions

The mountains appear in Shevek’s view of Anarres from two different directions. As the Mindful launches, he watches the field and the wall around the Port of Anarres recede, with the distant slopes of the Ne Theras beyond them, speckled with scrub holum and sparse, silvery moonthorn. The view places the mountains beyond the port’s boundary, in a landscape that is at once visible from the threshold and set apart from the world being left behind.

Later, on the third day of his dirigible journey, Shevek wakes as the aircraft clears the last high pass of the Ne Theras and turns south toward Abbenay. Looking down through a dusty window, he recognizes the walled field of the Port between two low, rusty ridges. The mountains thus frame his approach to the settlement as well as the departure he had witnessed from space: a route through their passes brings him back toward the port and the city beyond.

Ans Hos and the Promise of Eden

The region at the foot of the mountains has a history older than Anarres’s settlement. In the Third Millennium, astronomer-priests on Urras named Ans Hos, the Garden of Mind, for the place that turned green before other regions during the lunar new year. Later telescopes confirmed that it was indeed Anarres’s most favored spot. The first manned ship to the Moon landed in the green place between the mountains and the sea.

The promise of that first view proved misleading. Ans Hos, like the rest of Anarres, was dry, cold, and windy; the sun burned, the wind froze, and dust choked the thin air. The contrast between the name “Garden of Mind” and the lived environment makes the mountains part of a broader reversal: a landscape imagined from afar as Eden becomes a place of exposure and scarcity when experienced on the ground.

For two centuries after the first landing, Anarres was explored and mapped but not colonized. The change came when mining on Urras had depleted its lodes and rocketry made it cheaper to mine the Moon than to extract metals from low-grade ores or seawater. In the Urrasti year IX-738, a settlement was founded at the foot of the Ne Thera Mountains to mine mercury in old Ans Hos. Called Anarres Town, it was not a permanent town: men signed on for two or three years as miners or technicians and then returned to Urras.

A Boundary in Anarres’s Daily Life

The mountains also mark the scale and severity of Anarres’s environment. Abbenay lies beyond their passes, and winds from the Ne Theras can clear the dust haze that obscures its sky. During the dry winter described in the novel, water is rationed, food and clothing depend on holum plants, and the cloudless sky is often yellowed by dust carried from the south and west. When the wind blows down from the mountains, the haze lifts to reveal a brilliant, empty sky. The mountains are therefore not simply a distant outline: their weather helps shape how the city sees and endures the surrounding landscape.

Across these appearances, the Ne Theras connect Anarres’s port and urban settlements to its mining past and ecological limits. They offer a route through the planet, but not an escape from its conditions; the same mountains that shelter the celebrated Ans Hos also stand above a world of dust, cold, and scarcity.
