Nalenggele Valley — The Kunlun Gate of Hell
Where the northern edge of the Kunlun range folds down toward the Qaidam Basin, the valley of the Nalenggele River — a hundred kilometres of grass, marsh and gravel under six-thousand-metre peaks — is the place the herders will not enter: the Gate of Hell, where flocks starve on the outside rather than cross in; where the herder who went in after his horses in 1983 was found days later in a patch of scorched grass, his clothes shredded, no wound on his body; and where the scientific expeditions of the 1980s measured the valley's magnetism, lightning and frozen ground and called it geology — a verdict the herders have declined.

FILE 01 The Legend
The valley runs some hundred kilometres along the middle reaches of the Nalenggele River, its entrance near Buluntai off the southwestern rim of the Qaidam Basin, floor at three to four thousand metres between walls of the Kunlun. The herders' canon is older than any expedition: the valley eats what enters. Herds found dead on the flats without marks after overnight storms; wolves' fur and bears' bones scattered along the gravel; the standing instruction of generations — graze the flock to starvation on the outside before driving it through the Gate of Hell. The case that made the valley national canon came in 1983: horses from a ranch strayed in after the rich grass; a herder went in after them; the horses came back out on their own, and the herder did not. Searchers found him days later on a hillside — the story, retold for forty years, holds that his clothes were torn to shreds, his gun still in his hand, his face fixed in terror, the grass around him scorched black, and no wound anywhere on him. The expeditions followed through the 1980s and brought back a valley assembled from three mechanisms: bedrock of basalt threaded with magnetite, strong enough to swing a compass and, in the popular retellings, to reach absurd gauss figures; a summer thunderstorm engine — warm moist air funnelling into the high valley and nowhere to go but up — that concentrates lightning on the open floor, explaining herds dead after storms and scorched ground without marks; and beneath the summer grass, permafrost and bog deep enough that what falls through the summer melt never comes back. The pop-science verdict — mystery solved, it is geology — satisfied the magazines and not the mountains, and the herders' rule stands as it stood before anyone measured anything: the valley keeps what it takes.
FILE 02 The Sightings Log
The herders' accounts — herds dead in rows after storms, animals refusing the entrance at the cost of hunger, guides turning back at the valley mouth; expedition members reporting static in the air and instruments swinging over the ore ground; and the modern visitor's photographs of burnt patches, bone-littered flats and thunderheads standing over the valley on a clear day for the country around it. No systematic catalogue of the deaths exists, or ever has.
FILE 03 The Skeptic’s File
The valley is a textbook lightning trap and the explanations fit without remainder: magnetised basalt draws the storms' fury, open ground offers no shelter, strikes kill herds and scorch grass and can kill a man without leaving a wound a layman would recognise; the permafrost bog takes what falls. The pop articles' claims — valley-wide anomaly fields, gauss figures from ore veins extrapolated to the whole floor — overstate what the expeditions actually measured, and the 1983 herder details are decades of retelling thickened on a real death. Nothing recorded in the valley violates physics; everything recorded there punishes carelessness, at altitude, in the worst weather on the plateau. The gate of hell is a translation, not an instrument reading — but the herders' rule remains the correct one regardless of why.
