Titu Cusi gives no definite clue, but the activities of Friar Marcos and Friar Diego, who came to be his spiritual advisers, are fully described by Calancha. It will be remembered that Calancha remarks that "close to Uiticos in a village called Chuquipalpa, is a House of the Sun and in it a white stone over a spring of water." Our guide had told us there was such a place close to the hill of Rosaspata. On the day after making the first studies of the "Hill of Roses," I followed the impatient Mogrovejo--whose object was not to study ruins but to earn dollars for finding them--and went over the hill on its northeast side to the Valley of Los Andenes ("the Terraces"). Here, sure enough, was a large, white granite boulder, flattened on top, which had a carved seat or platform on its northern side. Its west side covered a cave in which were several niches. This cave had been walled in on one side. When Mogrovejo and the Indian guide said there was a manantial de agua ("spring of water") near by, I became greatly interested. On investigation, however, the" spring" turned out to be nothing but part of a small irrigating ditch. (Manantial means "spring"; it also means "running water"). But the rock was not "over the water." Although this was undoubtedly one of those huacas, or sacred boulders, selected by the Incas as the visible representations of the founders of a tribe and thus was an important accessory to ancestor worship, it was not the Yurak Rumi for which we were looking. ------ FIGURE Northeast Face of Yurak Rumi ------ Leaving the boulder and the ruins of what possibly had been the house of its attendant priest, we followed the little water course past a large number of very handsomely built agricultural terraces, the first we had seen since leaving Machu Picchu and the most important ones in the valley. So scarce are andenes in this region and so noteworthy were these in particular that this vale has been named after them. They were probably built under the direction of Manco. Near them are a number of carved boulders, huacas. One had an intihuatana, or sundial nubbin, on it; another was carved in the shape of a saddle. Continuing, we followed a trickling stream through thick woods until we suddenly arrived at an open place called ñusta Isppana. Here before us was a great white rock over a spring. Our guides had not misled us. Beneath the trees were the ruins of an Inca temple, flanking and partly enclosing the gigantic granite boulder, one end of which overhung a small pool of running water. When we learned that the present name of this immediate vicinity is Chuquipalta our happiness was complete.
