Which excerpt from "The Chenoo" suggests the story is a legend? Each day the two brothers would go hunting. The sister, whose name was Nolka, would stay behind to tend their camp and prepare any game caught the day before. On the third day, however, while out hunting, the brothers came across a very large set of footprints. Those footprints were over two feet long and ten feet apart. Meanwhile, back at camp, unaware of any danger, Nolka was busy cleaning an elk hide. Several yards away, in a large fire pit, a pile of rocks was being heated up for her brothers' evening sweat lodge. Walking over to the fire, Nolka picked up a large forked stick and carried one hot rock after another and began placing them in the center of the lodge. She was just pulling another rock out of the fire when she heard someone coming.
