Tlingit and Haida Tradition
Old-Woman-Underneath
In the Tlingit Raven cycle, the old woman beneath the earth who tends the post it rests on and controls the tides; when she is hungry the earth shakes, and Raven forces her to let the tide rise and fall.
Swanton's Sitka Raven cycle describes the earth as resting on a post attended by Old-woman-underneath (Hayicâ'nak!u). When she is hungry the earth shakes, and people put grease into the fire to send to her. She also controls the rising and falling of the water.
