Dr. Matthews gives the stories of the origin of several of the gentes. One story which he does not relate was told to me at Tohatchi, and serves to illustrate how a migration from the Northwest is transformed into a supernatural occurrence. Though told to me of the Navahoes as a whole, there can be no doubt that it applies only to a single gens. The story was in regard to Winged Rock, commonly called by the whites "Ship Rock," and about which I had been seeking information. This rock is situated in the Navaho reservation, about one hundred miles northwest of Tohatchi, and some fifteen or twenty miles from Carrizo Mountain. It is difficult of access, and my informant assured me that even though an army of white men should reach its base they could never scale its steep sides and reach its top. All the Navaho tribe reverence it sincerely and all watch and guard it jealously. He would indeed be a brave white man who would dare the anger of these warlike and brave natives if they forbade his approach and would attempt to scale this sacred Winged Rock. This was the legend: "Many, many years ago, when this country was young and the sun cast only small shadows, my people came across the narrow sea far away near the setting sun in the north and landed on the shores of this country. The people where they landed were exceedingly angry at them, and whenever they could they fell upon them and slew them. My people did not want to go to war, but this inhospitable reception made them angry, so they put themselves in war array and fell upon their foes. But there were few only of my people, and their enemies were so many that it was not long before they were in sad straits. Indeed, they would soon have been entirely destroyed had not help come. In their distress they called on Those Above, and soon a messenger from the sky came to my people and said: 'See you yonder stone mountain? Flee to it. It will be your salvation. Climb up its steep, strong, rugged sides and it will carry you toward the land of the South sea, nearer to the rising sun, and there your home shall be.' "My people were only too glad to obey the message. They hastened towards the mountain. Some who were weak were enabled to fly towards it like birds, and they clung to its steep sides and clambered to its top. "Then when they were all safe on its huge bulk, the monster rock was taken by Those Above, and it arose and floated across the rivers and plains and mountains and lakes and canyons. Several days and nights it floated, and my people gazed with wonder upon the strange and wonderful countries through which they travelled. Sometimes they thought they would like to stay in this place or in that, but the wisdom of Those Above said No! and the rock floated on. Oh! it was a glorious sail. Never before or since has any people been so blessed and favored by the People of the Shadows Above.
