Continuing westward, along the slope of the ridge, cut along its southern base by the Naches River, at a point about one and a quarter miles west of the mouth of the river, a small ravine cuts down from the top of the ridge. This has formed a little flat through the middle of which it has again cut down towards the river. East of this ravine on the flat is a circle of angular rocks such as are found scattered over the ridge. This circle no doubt marks a house site, the interior having been cleared of stone and the circle of rocks probably having been used to hold down the lodge covering.[18] To the west of the ravine, where the flat is somewhat higher than to the east, there are the remains of two semi-subterranean houses. Each of these is represented by a pit surrounded by a ridge of earth, and on the top, are large angular rocks.[19] At a point where the ridge meets this flat, close to the western side of the ravine was a slight depression in a small rock-slide which marked what seemed to be a grave, but which, on excavation, revealed nothing. Still further westward at a point probably two miles above the mouth of the Naches River and overlooking the stream at an altitude of perhaps 250 feet, we found scattered over the ground along the eastern summit of a deep ravine, the first one west of the house sites above mentioned, numerous small chips of material suitable for chipped implements. These became more numerous as we proceeded northward up the eastern side of the ravine for a distance of about a quarter of a mile. Here we came upon the small quarry in the volcanic soil, shown in [Fig. 1, Plate III]. Immediately to the west of the pit was a pile of earth, apparently excavated from it.
On the top of this heap of soil and among the broken rock to the south and east of it, were found several water-worn pebbles, used as hammers in breaking up the rock, as indicated by the battered condition of their ends ([p. 58]). We saw no other water-worn pebbles on the surface of the ridge, but they were numerous in the gravel of the bottom-lands subject to the overflow of the rivers. It would seem that these pebbles were brought up from the river below for use as hammers. Scattered to the south of the pit were found large fragments of float quartz material containing small pieces of stone suitable for chipped implements but made up mainly of stone which was badly disintegrated. Lying on the slope of the ravine were many small fragments of this same stone which were clear of flaws.
It would seem that a mass of float quartz much of which was suitable for chipped implements had been found here. It had been excavated, leaving the pile of earth and then broken up with the river pebbles which were left behind with the waste. Probably there were fairly large pieces of the material, suitable for chipped implements; that were carried away while small pieces were left lying about a pile of unsuitable material. In other words, it would seem that these specimens mark a place for the roughing out of material for chipped implements.[20] On the same side of the river, on the side of a rather low ridge or table-land overlooking it, at a point about twelve miles above its mouth, are some rock-slides. Here it is said that graves have been found. They were probably typical rock-slide graves. On a point of land perhaps fifty feet above these and a few hundred feet to the north, Master James McWhirter pointed out a grave on his farm. It was then surrounded by a ring made up of water-worn pebbles, apparently brought up from the river. He stated that an attempt had been made to excavate it which possibly accounts for the pebbles being in a circle rather than a heap over the grave. This grave was found to contain a slab of wood, shell ornaments, probably modern, and an adult skeleton, No. 12 (7), 99-4320, [p. 156].
There are a number of painted pictographs on the vertical faces of the basaltic columns, facing north on the south side of the Naches River, immediately to the west of the mouth of Cowiche Creek. These are below the flume and may be reached from the top of the talus slope which has been added to by the blasting away of the rock above, during the construction of the flume. In fact, debris from this blasting has covered part of the pictographs. Some of the pictures are in red, others in white and there are combinations of the two colors.[21] Local merchants have defaced these pictographs with advertisements.
In the Cowiche Valley, there are several rock-slide graves, but these seem to have been rifled. Northeast of the fair grounds at North Yakima, the remains of an underground house are said to exist. A short distance east of Tampico, about 18 miles above the mouth of the Ahtanum, on the north side of the river and east of the road from the north where it meets the river road and immediately across it from the house of Mr. Sherman Eglin, was a grave located in a volcanic dome left by the wind, which Mr. Eglin pointed out to us. The site is about 600 feet north of the north branch of the Ahtanum and about fifteen feet above the level of the river. A pile of rocks about eight feet in diameter covered this grave, No. 25, [p. 160]. On the land of Mr. A. D. Eglin, between the above-mentioned grave and Tampico on the north side of the road were seen the signs of two graves, destroyed by plowing. Near here, an oblong mound six or eight inches high and ten feet wide by eight feet long, supposedly covering a grave, marked by a stone on the level at each side and each end, 12 and 16 feet apart respectively was reported by Mr. Eglin's son. A little distance further north and up the slope of the land, were a number of volcanic ash heaps left by the wind. The surrounding land is what is locally known as "scab land." In some of these knolls, graves have been found and one which has been explored is shown in [Fig. 2, Plate IX]. It is located near the pasture gate, and was marked by a circle of stones as shown in the figure. On excavating, nothing was found. It is possible that the remains were entirely disintegrated. Graves in rock-slides on hill sides, and a village site near this place were reported by Mr. Eglin's son. Along the north side of Ahtanum Creek between Ahtanum and Tampico, below the rim rock of the uplands parallel to the creek are a number of rock-slide graves.
On the western side of Union Gap, through which the Yakima River flows, below the mouth of Ahtanum Creek, a short distance below Old Yakima, on a little flat or terrace projecting from the south side of Rattle Snake Range is a modern Indian cemetery surrounded by a fence. To the east of Union Gap, on the northwestern slope of Rattle Snake Range, we examined some rock-slide graves which had been made since the advent of objects of white manufacture. A mile or so south of Union Gap not far from the uplands to the east of the river was a ridge of earth extending north and south nearly parallel with the river road. This, however, I believe may be the remains of some early irrigation project. On the west side of the Yakima River about two miles south of Union Gap was seen a summer lodge made by covering a conical framework with mats.
At Fort Simcoe, immediately south of the Indian agency, on the north edge of the "scab land," overlooking a small ravine, is a large pit surrounded by an embankment of earth, the remains of a semi-subterranean house. Perhaps an eighth of a mile south of this, on higher "scab land" was a rather low long mound upon which were several piles of stone that probably marked graves. This mound was lower and more oblong than the usual dome in which such graves were made. Mrs. Lynch, who pointed these out has excavated similar piles at this place and found them to mark graves. We were informed that chipped implements were frequently found along the Yakima River at a point near Prosser. Above Kennewick, while digging a flume, a number of graves were discovered, from which Mr. Sonderman made his collection. Some of these graves contained modern material ([p. 111]).
On the surface of the western beach of the Columbia at Kennewick and on the flat land back of it we found chips of material suitable for making chipped implements, and a large pebble, probably a net sinker.[22] These, together with the fact that Mr. D. W. Owen has also frequently found specimens here, suggest that this place was an ancient camping ground. That Lewis and Clark saw Indians here and in the vicinity, as well as that the Indians still camp here on the beach of the river, sheltered from the wind by the bank and depending upon the river driftwood for their fuel, strengthens this suggestion. Specimens have been found on the large island in the Columbia at the mouth of the Yakima. (See [p. 64].) At a point four miles below Kennewick or perhaps a mile below a point opposite the mouth of the Snake, a grave which contained material of white manufacture is said to have been discovered by a man while hauling water up the bank of the Columbia.
Schoolcraft states[23] that there was an earthwork on the left bank of the Lower Yakima on the edge of a terrace about fifteen feet high a short distance from the water. This terrace was banked on either side by a [gully]. This consisted of two concentric circles of earth about eighty yards in diameter by three feet high, with a ditch between. Within were about twenty "cellars", situated without apparent design, except economy of room. They were some thirty feet across, and three feet deep. A guide stated that it was unique and made very long ago by an unknown people. Outside, but near by, were other "cellars" in no way differing from the remains of villages of the region. What may be an earthwork near by is described by Schoolcraft[24] as follows: "The Indians also pointed out, near by, a low hill or spur, which in form might be supposed to resemble an inverted canoe, and which he had said was a ship." Schoolcraft suggests a possible relation of this to the mounds of the Sacramento Valley and continues:—
"In this connection may also be mentioned a couple of modern fortifications, erected by the Yakamas upon the Sunkive fork. They are situated between two small branches, upon the summits of a narrow ridge some two hundred yards long, and thirty feet in height, and are about twenty-five yards apart. The first is a square with rounded corners, formed by an earthen embankment capped with stones; the interstices between which served for loop-holes, and without any ditch. It is about thirty feet on the sides, and the wall three feet high. The other is built of adobes, in the form of a rectangle, twenty by thirty-four feet, the walls three feet high, and twelve to eighteen inches thick, with loop-holes six feet apart. Both are commanded within rifle-shot by neighboring hills. They were erected in 1847 by Skloo, as a defence against the Cayuse. We did not hear whether they were successfully maintained, accounts varying greatly in this respect. In the same neighborhood Captain M'Clellan's party noticed small piles of stones raised by the Indians on the edges of the basaltic walls which enclose these valleys, but were informed that they had no purpose; they were put up through idleness. Similar piles are, however, sometimes erected to mark the fork of a trail. At points on these walls there were also many graves, generally made in regular form, covered with loose stones to protect them from the cayotes, and marked by poles decorated with tin cups, powder-horns, and articles of dress. During the summer the Indians for the most part live in the small valleys lying well into the foot of the mountains. These are, however, uninhabitable during the winter, and they move further down, or to more sheltered situations. The mission which, in summer, is maintained in the A-tá-nam valley, is transferred into that of the main river."[25]
