The northern boundary of the Nongatl begins in the west near Kneeland at the Wiyot boundary and runs southeast around Iaqua Buttes and the drainage of the Mad River, then northeast to Grouse Creek. Kroeber and Merriam agree on this boundary east of Iaqua Buttes, but west of that landmark Merriam's line takes a northeast-southwest direction whereas Kroeber's line runs due east-west. I have accepted Merriam's line here because he has more detailed information than Kroeber on the neighboring Whilkut. Neither has much information on the Nongatl themselves. One of the main interior lines of the Athabascans is the one which, running north and south along the South Fork of the Eel, divides the coastal groups on the west from the interior peoples to the east. It begins at the mouth of the Van Duzen on the main Eel and runs south along the Eel as far as Scotia, dividing the Nongatl from the Bear River group. At Scotia it coincides with the Sinkyone-Nongatl boundary and then continues in a southerly direction but, instead of lying immediately on the river, it drifts slightly to the east to include also the land adjacent to the stream. It continues thus near to, but off, the main Eel until it crosses the river at about McCann, a few miles above the mouth of South Fork. After crossing the main Eel, the line goes south, including the immediate river valley of the South Fork of the Eel in Sinkyone territory, until it turns west to cross South Fork at the mouth of Hollow Tree Creek, continuing to the coast at Usal Creek. This section of the Athabascan boundary has been much disputed. It seems certain that the western side of the Eel from the mouth of the Van Duzen to Scotia was Bear River territory. This distribution is attested by Powers (1877, p. 107), who says that the Bear River group owned as far south as the mouth of South Fork, by Nomland's Bear River informant (1938, map 1), by Kroeber, and by Goddard, who says (1929, p. 291), "There was, however, one village at the mouth of Van Duzen creek which was allied to Bear River both in its dialect and politically." This evidence is fully in accordance with that of Merriam. The eastern side of the river along this stretch goes to the Nongatl by default. Kroeber claims it for the Bear River people and Nomland's Wiyot informant claimed it for the Wiyot (Nomland and Kroeber, 1936, map 1) but except for these sources possession is denied by Wiyot, Bear River, and Sinkyone alike. South of Scotia the area is also in dispute. Nomland and Kroeber claim that the eastern side of the Eel from Scotia to the mouth of South Fork is Nongatl. They say (1936, p. 40): In any event, Eel river from Scotia to Larrabee was not Mattole, as Kroeber has it in map 1 of his Handbook, nor was it Sinkyone. Nomland's Bear River, Mattole, and Sinkyone informants were positive on the point. If Athabascan, the stretch in question belonged to the Nongatl (Saia). Otherwise it was Wiyot.
