Medicine dolls have been around for a long, long time. This one is from St Lawrence Island in Alaska. It is thousands of years old. The indentations you can see are on the back also. It appears to have been well used, too. As you can see, it is a female. The carver used fossil walrus ivory. That is apparent from the use of the color which may have formed a cloak of some sort, very interesting.
In my second book in the series, Against All Odds, Pheleta brings it down from north with other little treasures. Shown above is a bola and a bone awl which she uses in the book. She is a messenger and a healer who goes from village to village up north on a dog sled with three dogs. She accidentally turns down the ice corridor and winds up in the south west!
