The Archaeology of the Yakima Valley

The following pages contain the results of archaeological investigations carried on by the writer for the American Museum of Natural History from May to August, 1903,[1] in the Yakima Valley between Clealum of the forested eastern slope of the Cascade Mountains and Kennewick, between the mouths of the Yakima and Snake Rivers in the treeless arid region, and in the Columbia Valley in the vicinity of Priest Rapids. My preliminary notes on the archaeology of this region were published in Science.[2] Definite age cannot be assigned to the archaeological finds, since here, as to the north, the remains are found at no great depth or in soil the surface of which is frequently shifted. Some of the graves are known to be of modern Indians, but many of them antedate the advent of the white race in this region or at least contain no objects of European manufacture, such as glass beads or iron knives. On the other hand, there was found no positive evidence of the great antiquity of any of the skeletons, artifacts or structures found in the area. The greater part of the area was formerly inhabited by Sahaptian speaking people, including the Yakima, Atanum, Topinish, Chamnapum, and Wanapum, while the northern part of it was occupied by the Piskwans or Winatshmpui of the Salish linguistic stock.[3]

Near North Yakima we examined graves in the rock-slides along the Yakima and Naches Rivers; a site, where material, possibly boulders, suitable for chipped implements had been dug and broken with pebble hammers, on the north side of the Naches about one mile above its mouth; pictographs on the basaltic columns on the south side of the Naches River to the west of the mouth of Cowiche Creek; petroglyphs pecked into basaltic columns in Selah Canon; ancient house sites on the north side of the Naches River near its mouth, and on the north side of the Yakima River below the mouth of the Naches; remains of human cremations, each surrounded by a circle of rocks on the point to the northwest of the junction of the Naches and Yakima Rivers; recent rock-slide graves on the eastern side of the Yakima River above Union Gap below Old Yakima (Old Town); the surface along the eastern side of the Yakima River, as far as the vicinity of Sunnyside; graves in the domes of volcanic ash in the Ahtanum Valley near Tampico; and rock-slide graves in the Cowiche Valley.

We then moved our base about thirty miles up the Yakima River to Ellensburg, Mr. Albert A. Argyle examining the surface along the western side, en route. From Ellensburg, rock-slide graves and human remains, surrounded by circles of rocks, as well as a village site upon the lowland, were examined near the mouth of Cherry Creek. A day spent at Clealum failed to develop anything of archaeological interest in that vicinity, except that a human skeleton had been removed in the sinking of a shaft for a coal mine.
