The Chilula (Yurok language term: Chueluela' / Chueluelaa' , Tsulu-la, "People of Tsulu, the Bald Hill", locally known as the "Bald Hills Indians") were a Pacific Coast Athabaskan tribe speaking a dialect similar to the Hupa to the east and Whilkut to the south, who inhabited the area on or near Lower Redwood Creek, in Northern California.
Upstream and northwest of the Whilkut along the Lower Redwood Creek lived the Chilula; they established their more than 20 villages only along the eastern shore, because there the mountains were broken by valleys irrigated by small streams, while the western shore was difficult to access.
The Chilula (together with Whilkut) were called by the neighboring Hupa-speaking peoples Xwiy¬q'it-xwe / Xwe:yłq'it-xwe ("Redwood Ridge / Bald Hills People"), the Karuk also called them Vitkirik'áraar ("People of Viitkírik/Viitkírak (Bald Hills)"), therefore they were also known as Bald Hills Indians or Lower Redwood Indians.
The Chilulas also had temporary camps on Bald Hills, where they stayed during the summer and fall.
Small pieces of leftover wood were used to make drum frames, medicine boxes, and other items.
