LEONHARDY Laboratory of Anthropology Washington State University ABSTRACT The Iron Gate site is a single component village located on the Klamath River is Siskiyou County, Cali- fornia. On the basis of radio-carbon dates occupation is estimated to have been between 1400 A.D. and 1600 A.D. The excavated houses were conical, bark-covered structures differing from the house type re- corded in the area in historic time but resembling those recorded further south. Artifacts, particularly pro- jectile points, are similar to those found in northwestern California and Oregon. Stone working traditions appear more closely related to those of the Klamath Lakes and Columbia Plateau regions of Oregon than to those of central California. Analysis indicates patterns of community organization and economy virtually identical to those of the ethnographic period. The site is considered representative of a phase in Shasta culture history even though direct historical connections cannot be established. In terms of cultural affilia- tions on a larger scale, the culture represented by the Iron Gate site is viewed as transitional between the Columbia Plateau and central California. There is no evidence of close affiliations with the cultures of the northwest California coast. INTRODUCTION The Iron Gate site is one of three sites dis- covered by a University of Oregon survey of the Iron Gate Reservoir in Siskiyou County, Cali- fornia. It is a small village situated on a ter- race on the south hank of the Klamath River about 100 meters above the confluence of the Klamath River and Jenny Creek. The location is in the SEl4 of the NEl4 of Sec. 34, T48N, RSW, Mt. Diahlo Meridian, only three miles south of the Oregon border and nine miles east of Hornbrook, California (Fig. 1). On the east end of the terrace were thirteen house pit depressions varying from 6 to 10 meters in diameter and 20 to 50 centimete;rs in depth. Most depressions had clusters of rocks in the center and, occasionally, on the edge. Cultural debris was visible on the surface. No house pits were found on the west end of the terrace, although artifacts were found in an eroding hank. Because of time limitations, ex- cavation was limited to the house pits. Vegetational cover on the site was grass and sagebrush; around the site, and in the immedi- ate vicinity, grow manzanita, mountain mahog- 2 BULLETIN, MUSEUM OF NATURAL HISTORY, UNIVERSITY OF OREGON No.4 124° 123• 122• 121• 120• 43 + .!-1 + + O Crater Lake G ;· Upper Klamath Lake Medford Klamath Fall, lflPJt-ffil - -1- -o --, Hornbrook K 60011 Lake I "' ..

The vegeta- tion of the area may be classed in the Transi- tion Life Zone (Bailey, 1936) . Animal life observed was varied and plentiful. Deer are surprisingly numerous, but to what extent this might reflect the aboriginal condition is not certain. Among the smaller mammals noted were rabbits, skunks, marmots and ground squirrels. Reptiles observed were turtles, small lizards and a variety of snakes. Crayfish, mus- sels and trout are plentiful in the river and salmon and steelhead migrate in large num- bers. The birds observed included blue herons, buzzards, and a diving duck. Crews from the University of Oregon worked at the site on two separate occasions: from June 11 to June 21 and from September 5 to September 14, 1960. During the first session House Pits 1 and 2 were partially excavated and House Pit 3 was tested. During the second session House Pit 4 was completely excavated and additional work was done in House Pit 2. In all, 785 artifacts, details of 11 house floors and abundant cultural debris were recovered. Comparative data are not plentiful for there are few excavated sites in northwestern Cali- fornia and southwestern Oregon.1 Sites which have been excavated are usually of limited time depth and the artifacts are not greatly different from ethnographic material culture. Archaeo- logical data on prehistoric houses in the region are virtually non-existent and, as a conse- quence, the discussion of the Iron Gate houses depends almost exclusively on ethnographic data. The site is located in the eastern part of the tribal area of the Shasta Indians. To the east was the boundary between the Shasta and the Modoc; to the north, generally following the summit of the Siskiyou Mountains, was the boundary between the Shasta and the Takelma. To the south and southeast the Shasta were in contact with the Wintu and Achomawi; to the west, down river, they were in contact with the Karok and, through them, the Y urok. Kroeber ( 1939: 55) classed Shasta culture as transi - tional between the Northwestern Californian and Central Californian Culture Provinces and Holt (1947: 348) described it as basically Central Californian but having developed under strong influences from Northwestern California. ACKNOWLEDGEMENTS Field work in the Iron Gate Reservoir was supported by grants from the California-Ore- gon Power Company ( now the COPCO Divi- sion of Pacific Power and Light Company). To COPCO, Mr. J. C. Boyle, Vice-President and General Manager, and Mr. Robert L. Byer, Project Engineer, I express thanks. Members of the crews who worked at the site were Mr. and Mrs. Don L. Dumond, Lionel A. Brown, 1 Since completion of the Iron Gate Project, the Univer· sity of Oregon conducted a three-year program of excavation along the Klamath River in the Salt Caves Reservoir area, only a few miles upstream from Iron Gate. The data recovered by the Salt Caves Project have not yet been completely ana· lyzed and are not available for detailed comparison. The col· lections were examined in January, 1966, and no information which would alter the conclusions of this report was found. Indeed, LeRoy Johnson, Jr., (personal communication) feels that some of the houses in the Salt Caves area are closely comparable to those herein reported. ----~- - f i, i, 1967 LEONHARDY: ARCHAEOLOGY OF A PREHISTORIC VILLAGE 3 Plate 1.

Lehman and James Gillis; David L. Cole was field director. The hospitality of Mr. and Mrs. Al Kutzkey made our stay on the Klamath River a memorable one. This report is a condensed and modestly re- vised version of a 1961 Master of Arts thesis written under the direction of Dr. L. S. Cress- man. The guidance of Dr. Cressman and the assistance of David L. Cole and W. Raymond Wood are sincerely appreciated-all were ex- tremely generous with their time and experi- ence. Dr. J. Arnold Shotwell identified the mammal remains from the site; Dr. Loye Mil- ler identified the bird remains; and Dr. Leroy Detling identified the botanical specimens. Mr. James Lehman prepared the artifact illustra- tions used in Figures 12 ( d-g) and 14. I also express appreciation to Deward E. Walker, Roald Fryxell, Mrs. Barbara Purdy and David Rice for reading and criticizing various parts of the revised manuscript. James Lehman pre- pared the illustrations used in Figures 1-14, 16-17; Roald Fryxell made the drawing of the reconstruction of the Iron Gate house type (Figure 15 and cover). 4 BULLETIN, MUSEUM OF NATURAL HISTORY, UNIVERSITY OF OREGON No.4 KLAMATH R I V E R ---- ..... 96.00 97.00 98.00 99.00 100.00 I I ,.. ..._ (-', HOUSEPIT DEPRESSIONS .... .,,, EXCAVATED AREAS CONTOUR INTERVAL ONE METER Figure 2.

DESCRIPTIVE ARCHAEOLOGY ExcA v A TION TECHNIQUES Although the house floor was the primary unit of excavation, a grid of 2-meter squares was established on the site to facilitate hori- zontal control. Excavation of each floor pro- ceeded one square at a time in order to mini- mize any error and to provide an accurate record of artifact provenience. All fill was sifted through 4-mesh screens to insure com· plete recovery of artifact material and cultural debris. The surfaces of the house pits to be exca- vated were first cleared of grass and brush and the sod was removed; any large stones associ- ated with the surface were left in situ. At first an attempt was made to find the rim of House Pit 1 by excavating one square by arbitrary 10-centimeter levels. A rim was found, but higher floors which had not been distinguished during excavation were found in the profiles. A second test pit was then excavated in the center of House Pit 3 to determine the char- acteristics of the floors, the location of firepits, and a possible sequence of floors. On the basis of information about the composition of house l -/ ABM pits gained from the tests, the technique adopted was to begin excavation in the center, find the top floor, and then follow it to the out- side of the pit. Because floors were generally more distinct in the center where they were marked by a layer of ash or an abrupt change in fill, this method proved successful. During excavation the floors in each house pit were numbered in sequence from the top. In this report, however, the floors have been renumbered in sequence of occupation. Thus, Floor 1 in each house pit is the lowest, and earliest, floor. HOUSES The houses at the Iron Gate site differ from those used in the area during the ethnographic period. Shasta houses were basically rectangu- lar plank structures, whereas the Iron Gate houses were circular, bark-covered structures. Further, the Iron Gate houses differ in details of construction from the circular houses found upriver among the Klamath and Modoc. The data described below indicate a house form very similar to the conical, bark-covered house which had a wide distribution in northern California. 1967 LEONHARDY: ARCHAEOLOGY OF A PREHISTORIC VILLAGE 5 Plate 2. House Pit 1 before excavation. Note the cluster of rocks in the center of the depression. HOUSE PIT 1 SURF ACE FEATURES: In the center of the de- pression was a cluster of 12 rocks ranging in size from 15 x 15 cm. to 30 x 50 cm. None were artifacts. Directly beneath the rocks, but sepa- rated from them by 3 to 4 cm. of fill, was a firepit associated with Floor 3. FLOOR 3 (Fig. 3): Maximum diameter: 5.25 m. Depth from surf ace: 5 to 15 cm. Description of firepit: An oval, rock-lined firepit 40 cm. long, 25 cm. wide and 4 cm. deep was centrally located. It was surrounded by a large, thin layer of ash. Features noted: The remains of two large, incompletely burned pieces of wood, large pieces of charcoal and fragments of burned bark were found in the northwest quadrant. Small pieces of charcoal and burned bark marked the rim on the west and south sides of the floor. A mano, a metate, and a hopper mor- tar stone were closely associated in the north- east quadrant. FLOOR 2 (Fig. 3): Maximum diameter: 6 m. Depth from surf ace: 15 to 35 cm. Description of firepits: ( 1) A layer of ash, as much as 5 cm. thick, covered the center of the floor. This was directly beneath, but sepa- rated from, the ash covering Floor 3. ( 2) An oval firepit, 52 cm. long, 40 cm. wide and 5 cm. deep, was located on the south side of the floor. The earth around it was oxidized to a bright orange color. ( 3) An area of ash and burned earth approximately 45 cm. long and 35 cm. wide was near the rim in the southeast quadrant associated with burned bone, antler, and wood. Features noted: There were two very dis- tinct layers of fill between Floor 3 and Floor 2. The uppermost of these was a discontinuous stratum of hard, yellowish-colored fill which lay around the circumference of the pit extend- ing inward a maximum of 2 meters. In plan view this layer was generally circular; the out- side edge, although irregular, generally coin- cided with the rim of the floor; the inside edge was very irregular and not always well defined. The cross section was lenticular, about 10 cm. thick at the outside, tapering toward the inside. This stratum could have been formed by earth falling into the pit from around the outside. If the house had burned and collapsed, an oc- currence for which there is good evidence, then any earth banked up on the outside would have fallen into the pit, forming a circular band of fill such as this stratum. Beneath the hard fill, and immediately above the floor, was a layer of loose, black dirt containing large numbers of bone fragments and artifacts. Part of the southwest quadrant was covered with partially burned bark which lay just above the floor beginning at the rim and ex- tending into the pit ( Fig. 3; Plate 3). Under the bark were the remains of at least three wooden beams or poles. The bark was not well enough preserved to permit specific identifica- 6 I I I I I I I I \ BULLETIN, MUSEUM OF NATURAL HISTORY, UNIVERSITY OF OREGON No.4 .
