This story appears in an issue of Fantastic Universe with a remarkable lineup including Frank Belknap Long, Philip José Farmer, Jack Williamson, Philip K. Dick, Richard Matheson, Marion Zimmer Bradley, and Robert Bloch. As for Kuttner’s contribution, a crippled priest enlists the aid of an adventurous anthropologist, Señor White, to track the fate of seven young girls who disappeared into the Cordilleras of eastern Peru in the direction of the great peak, Hauscan. Do anthropologists know anything about time-slips? (Yes, just a slight time-travel connection.)
So, even now I do not know all that lay behind the terror in that Peruvian valley. This much I learned: the Other, like Lhar and her robot, had been cast adrift by a time-slip, and thus marooned here. There was no way for it to return to its normal Time-sector. It had created the fog-wall to protect itself from the direct rays of the sun, which threatened its existence.
