Details regarding the twenty-two kiloton device were scarce, but the US regarded the development as an unwelcome wrinkle in the already precarious Cold War. Officials from India were also distressed, having felt the business end of China's military during a recent border dispute. In the interest of self-preservation, the two nations made a secret pact to combine their China-watching efforts. Photo reconnaissance satellites were still too primitive for practical spying, and high-flying surveillance planes were too conspicuous, but there was one alternative vantage point. The intelligence agencies hatched a nefarious scheme to keep a sharp eye on China's weapons tests from atop India's Nanda Devi, one of the tallest mountains of the imposing Himalayan mountain range. It offered an unobstructed view of China's distant test site, assuming one could manage to hoist a sufficiently powerful electronic eye to its summit.
Several months after the Chinese nuclear test, a young doctor at the University of Washington Hospital in Seattle was doing his rounds when he heard his name paged over the intercom. Upon his arrival at the front lobby, he was confronted by an sinister-looking man clad in dark glasses and a trench coat.
The CIA, he explained, was seeking a physician with experience in electronics and mountain-climbing, a combination of requirements which produced relatively few candidates. Schaller satisfied all of the criteria, having become obsessed with climbing over the previous few years. In exchange for his service and silence, the agency offered $1,000 per month; a considerable stipend at the time. Unable to resist the generous salary, the once-in-a-lifetime mountaineering opportunity, and the prospect of patriotic employment, he hastily agreed. His training was scheduled to begin almost immediately.
Over time Dr. Schaller's colleagues at the hospital grew curious regarding his recent rash of conspicuous absences. He often returned having lost a few pounds and gained a few injuries, but when pressed for an explanation he was evasive. His official cover story was that he was being trained as a scientist-astronaut, but he declined to elaborate. The true nature of his outings was a closely guarded secret, withheld even from his own family.
Each training mission began by venturing into a canvas tunnel which led to an airplane with blacked-out windows. Often Schaller traveled with an assortment of citizen-spy companions, including Tom Frost, a climber famed for his Yosemite exploits; and expedition leader Captain Mohan Singh Kohli, a mountaineer renowned for his Everest expeditions. Many of the others were unfamiliar to Schaller, but he reasoned that they were scientists or professors, considering their knowledge of nuclear technology. Over a period of months he and the other operatives became acquainted with the subtleties of leaping from helicopters, demolishing targets with plastic explosives, and handling the experimental atomic-powered hardware which was developed specifically for their mission. Also, to prepare for the climb ahead, the men were required to repeatedly drag the equipment up the formidable cliffs of Alaska.
Together the dozen climbers and Sherpas slowly scaled the side of the Goddess. By day the extra equipment hindered their upward progress, but by night the atomic contraption provided a pocket of warmth for the adventurers. Nestled within the forty-pound generator was sufficient plutonium to power the surveillance package for a thousand years, thereby providing the US and India with uninterrupted observation of Chinese nuclear bombs and Inter-Continental Ballistic Missile (ICBM) tests.
For several days the crew clambered up the face of Nanda Devi as Dr. Schaller cataloged the journey with his camera and diaries. The gaggle of makeshift secret agents crossed the crevasse-riddled glaciers with the help of steel-spiked shoes and ice axes, gradually making their way to High Camp-- the last stop before the summit. The Goddess' perilous peak stood a mere 1,000 feet above them. But as the team settled in, the sky around Nanda Devi grew dark and restless. The frigid air mingled with moisture, and the stew swiftly thickened into a surly autumn blizzard.
Faced with the threat of being whisked away by the atmospheric tantrum, expedition leader Captain Kohli concluded that the team must turn back, postponing the mission until the spring climbing season. Kohli ordered that the surveillance package be lashed to the mountainside, much to the surprise and chagrin of his fellow climbers. He reasoned that the team could reacquire the equipment on the next ascent rather than hauling it up the mountain again. The team secured the antenna, two transceiver sets, and nuclear generator on a rocky outcropping, then hastily fled from the detestable weather.
No one could be certain what would become of the core in the glacier's clutches, but there was cause for great concern. There were two equally alarming prospects: the nuclear fuel might fall into the wrong hands, leading to any number of diabolical designs; or the slab of migrating ice might slowly grind the plutonium into a paste and deposit it into the Sanctuary melt waters, shuttling the four pounds of radioactive material into the vital Ganges River.
For the next two years, the CIA sent scores of Geiger-counter-carrying climbers and specially-outfitted helicopters to comb the ice fields for any trace of the powerplant. Meanwhile, Schaller and his team scaled a neighboring mountain and successfully installed a similar explosion-observing, missile-monitoring apparatus. They then joined the search efforts to locate the misplaced plutonium, but aside from a few Geiger-counter clicks, there was not a trace to be found. The prolonged search did, however, afford Schaller the opportunity to finally summit the elusive Nanda Devi; he stole away from High Camp during the pre-dawn hours for an unauthorized climb. Ever the documentarian, Schaller snapped a photo of himself at the summit for posterity.
As the final Himalayan expedition drew to a close, the team's official government operative asked to borrow Schaller's photographs and journals to help him file the mission report. Dr. Schaller happily complied, but after several months the documents remained unreturned. His subsequent requests for the materials were rebuffed, the CIA citing the need for security. Additionally, the doctor was awarded the Intelligence Medal of Merit for his contributions, but the two agents who presented the medal in a private ceremony were not allowed to leave the medal with him. Even today, decades after the espionage operations, Schaller's requests for his documents are met with letters stating that "the CIA can neither confirm nor deny the existence or non-existence of records responsive to your request."
To the best of Dr. Schaller's knowledge, the Central Intelligence Agency never managed to reacquire their missing nuclear appliance. But a water sample from the Sanctuary in 2005 showed troubling hints of plutonium-239, an isotope which does not occur naturally. Years, decades, or centuries from now, the corpse of the rogue generator may yet rise from its icy grave and exact a radioactive revenge upon humanity. However, the CIA can neither confirm nor deny the existence or non-existence of a disaster approximating the aforementioned depiction.
