Meanwhile, as noted in the last chapter, our own party had passed the Crossing of the Fathers, had arrived at the mouth, of the Paria, and, according to our plans, had cached our boats there for the winter while we proceeded to inaugurate our land work of triangulation.  A number of us were left for a while in camp in a valley lying between the Kaibab Plateau, then called Buckskin Mountain, and what is now called Paria Plateau, at a spring in a gulch of the Vermilion Cliffs.  Two large rocks at this place had fallen together in such a way that one could crawl under for shelter.  This was on the old trail leading from the Mormon settlements to the Moki country, travelled about once a year by Jacob Hamblin and a party on a trading expedition to the other side of the river.  Somebody on one of these trips had taken refuge beneath this rock, and on departing had written, in a facetious mood, along the top with a piece of charcoal, “Rock House Hotel.”  Naturally, in referring to the spring it was called, by the very few who knew it, Rock House Spring, and then the spring where the House Rock was, or House Rock Spring.  From this came House Rock Valley, and the name was soon a fixture, and went on our maps.  And thus easily are names established in a new country.  All around were evidences of former occupation by the Puebloans, and I became greatly interested in examining the locality.  At length, we were ordered across the Kaibab to the vicinity of Kanab, and I shall never fail to see distinctly the wonderful view from the summit we had of the bewildering cliff-land leading away northward to the Pink Cliffs.  The lines of cliffs rose up like some giant stairway, while to the south-eastward the apparently level plain was separated by the dark line of Marble Canyon.  On top of the plateau, which was covered with a fine growth of tall pines, we came about camping time to a shallow, open valley, where we decided to stay for the night.  As it was on the top of the mountain Bishop recorded it in his notes as Summit Valley, and so it ever afterward remained.  There was no spring, but a thin layer of snow eked out the water we had brought in kegs on the packs, and we and the animals were comfortable enough.  The trail had not been travelled often, and was in places very dim, but we succeeded in following it without delay.  The Kaibab, still frequently called the Buckskin Mountain, must have received this first name from its resemblance to a buckskin stretched out on the ground.  The similarity is quite apparent in the relief map opposite page 41.  As it was the home of the Kaibab band of Pai Utes, Powell decided to rename it after them.  We arrived within eight miles of Kanab, where we made a headquarters camp at a fine spring, and trips from here and from a camp made later nearer Kanab were extended into the surrounding country.  The Mormons had a year or two before come out from the St. George direction and established this new settlement of Kanab, composed then of a stockaded square of log houses and
