Between the two mountain chains lies a basin of plateau and highlands known as the Altiplano, or high tableland, extending over five hundred miles north-to-south and varying in elevation from twelve to fourteen thousand feet. The northern part of the Altiplano, bordering Lake Titicaca and containing the seat of government, La Paz, is the industrial hub and home to the bulk of the population. Nowhere else does such an industrial area, with cities, railroads, and highways, exist at such an altitude. The southern Altiplano is more arid and barren, consisting of vast salt wastes and rolling plains of steppe vegetation broken by fingerlike remnants of eroded escarpments standing between deep river valleys and basins.
The Spaniards began mining in the sixteenth century, finding large deposits of silver that made Potosí the largest and richest city in the New World at the time. Although later centuries saw developments in the extraction of tin, bismuth, tungsten, antimony, lead, zinc, iron, and copper from accumulations of volcanic ash and ancient sediments, much of the region’s mineral potential remained untapped because of political instability and want of capital investment. Then the Hyadeans moved in, and applying such techniques as nuclear-driven particle beam mining, and plasma ionization with magnetic separation, which no Terran operation could rival, began exploiting on a massive scale fabulous deposits along the inner slopes of the Cordillera Occidental in the southernmost reaches of the country. They sold the processed minerals to Terran manufacturing industries in exchange for land-purchase currency on terms highly profitable for the Terran enterprises concerned and also for the national land-management agencies. Development of transportation northward opened up the Amazon route for exporting processed minerals, especially to Europe, and a newer, current project involved blasting a tunnel through the Cordillera Occidental to a new shipping and handling facility being constructed at Iquique in Chile.
The Hyadean residential settlements were farther north in the more picturesque parts of eastern Peru and the highlands in the tip of Brazil, west of Amazon basin. Their main spaceport for connection to the interstellar ships parked in orbit was at Xuchimbo, in western Brazil, near the point where the borders of the three countries meet. The Hyadean presence had brought a prosperity boom to local businesses, and workers and unions were more than happy with the wages. This provided a broad popular base of political support for the Hyadean-backed government operations being conducted against the insurgency forces active throughout the area.

Cade’s reality—the accumulation of perceptions and experiences that he lived in—had always reflected the world of the affluent and the comfortable. Having taken twenty-first-century global communications for granted as part of growing up, he had paid a token concession at the intellectual level to the existence of other places ruled by other conditions; but despite the background detail woven into movie presentations and the vividness of travel documentaries, the places he acknowledged at that detached level of awareness had never before, somehow, taken on the deeper, emotional quality that brings on a sense of being real.
“Vast,” “rugged,” “empty” were the words that formed in his mind as he took in the cabin displays while the SST slowed for its vertical descent into the landing zone. It was now late in the day. To the west, broken ramparts of reds, browns, yellows and grays, rising in ranks of fading ridges to a line of snowy peaks barely visible in the distance, were darkening against the background sun. Arid hills and rocky basins extended away north and south, opening out and leveling eastward into barren salt flats. Amid it all stood the installations at Uyali.
Uyali was Hyadean-built to serve as the center of their extraction operations, sprung out of the Altiplano desert south of previously worked Terran mining areas. On the western side was what Ni Forgar, who seemed to be some kind of engineer returning to base, said was the reduction and processing complex. With its metal domes, cylinders, and spherical constructions standing among large, white boxlike structures, it looked more like a refinery than what Cade would have expected, though with less clutter and piping. It seemed ugly and sprawling, but visiting Terran engineers had apparently been amazed at its compactness for the volume of material that it handled. This arrived by way of two gigantic moving-belt conveyors converging in a V across the landscape, carved through hills and spanning canyons until they were lost from sight; farther on, Forgar told them, the root conveyors divided repeatedly to form a branching tree probing its way through to extraction points scattered among the mountains. He described the processing complex with typical Hyadean bluntness, never slow to make a point of what he thought they did better.
