The eastern boundary of the Matt[=o]l´ I was unable to locate exactly. They gave it as along or near the west base of Elk Mountain Ridge, including the Valley of Upper North Fork Mattole River. At the same time they gave the names of two 'tribes' or bands as inhabiting the Rainbow Ridge and Elk Ridge region. The Elk Ridge tribe they call S[)a]-bahng-kahng, the Rainbow Ridge people S[)e]-tso´-ik (from S[)e]-tso-[=e]k, Rainbow Peak). There is uncertainty as to the relations and geographic locations of these bands. The tribe inhabiting the coast at Needle Rock they call E´-l[)e]-tung. It is the same as the Shelter Cove tribe. TRIBELETS According to Merriam's data, the people at Cooskie Creek in the southern part of Mattole territory form a distinct band. This agrees with Goddard's village data, and Goddard also assigns to this group some of the villages on the upper Mattole. There is no evidence of further subdivision. VILLAGES Most of the information on villages of the Mattole is taken from Goddard's notes. (See map 14.). In addition, there are a few data recorded by Merriam. Below, Goddard's information is indicated by (G), Merriam's by (M). 1. sitc[=i]b[=i]' (named from sand bar?) (G). On the S side of Domingo Cr. nearly a mile from the surf. The county road leaves the coast at this point. Plenty of signs of occupation but no definite pits. 2. sesnoik[=o]', "rocks stand up creek" (G). About 1/2 mi. E of the line of the surf, close to the hill through which the stream in McNutt Gulch comes from the SE. A large quantity of cooking stones and shells have been exposed by the blowing away of the soil. Salmon run in the creek. 3. sesn[=o]t, "rocks stand up" (G). N of a large rock which is 30 or 50 ft. higher than the surrounding sand. Another large rock stands 300 yds. W, with a chain of rocks and ledge running out into the surf. Many shells and stones mark the village site. This village stood in the middle of a 2-mi. stretch of sandy beach, which reaches from gotxenin to a mile N of this village. 4. sedjildaxdiñ (G). Close up under the hill. The wind has carried away the soil, leaving a great pile of shells. Just S, a stream comes down the hillside with only a gulch [La Rue Gulch], no valley. 5. gotxenin (G). Known to white people as Mussel Rancheria. On a bench with Peter B. Gulch at the southern end and La Rue Gulch in the middle. A great quantity of shells were to be seen but no pits. Joe said the houses were scattered along for nearly a mile. Many rocks are in the surf.
