Ts'im Anwiihlist means "inside the place of the big (oblong) dipnet". Though Ts'im Anwiihlist is part of the territory of a Sin'oogit/chief and his Wilp....it is also a common fishing and food gathering place for [all] the Nisga'a. Ts'im Anwiihlist is a migration spot for salmon. Ts'im Anwiihlist is also a Txeemsim landmark. As Txeemsim, the Grandfather of the Nisga'a, was walking down and creating the river Lisims (Nass River), a ghost whistled in his face when he reached this spot. This made Txeesim turn around and walk back momentarily, and then he turned around again to continue downstream. This accounts for the bend in the river at Ts'im Anwiihlist. It was also here where Txeemsim taught our ancestors how to make a dipnet; the bend in the river is also likened to the hook used to [pull] up the dipnet from the river.
