When grizzlies walked upright

This story is similiar to The Earth on Turtles back, they are both stories of how the earth was created. In this story there is a land of sky spirits with a cheif. In this land it grew extremely cold and snowy, so the cheif carved a hole into the ground. As time grew on, the snow created a mound that was from the earth to the tip of the sky. The cheif walked down the moutain, and started to touch everything he saw, this created trees and life. Everything he touched turned into something new. He created with his stick, grizzly bears. When they were first created they walked upright on two feet and they could talk like humans. But they looked so fierce that the sky spirits sent them away from him to live in the forest at the base of the mountain of snow. The chiefs daughter was ordered to talk to the wind spirit to tell him to blow gently, but she didnt listen to her father when he said dont stick your head out at the top of the mountain, so she did. She got blown away and a grizzy bear found her, they lived together the human and the bears. One day they got married and had several children, then the grizzly bears went in a herd to ask the father for forgivness for keeping there daughter from him all these years. The father was very glad but he was furious at the bears, so the father put a curse on the bears, and made the bears walk on all fours and made them so they couldnt talk. After that he took his daughter back to the sky spirits and lived on. The grizzly children turned into indians and that was how the world was made.
