In "Julie of the Wolves," how is Miyax described by the author?

The author describes Miyax's appearance directly four pages into the book.  She says,

"Miyax was a classic Eskimo beauty, small of bone and delicately wired with strong muscles.  Her face was pearl-round and her nose was flat.  Her black eyes, which slanted gracefully, were moist and sparkling...she was slightly short-limbed".

To describe Miyax's personality, the author uses a different method.  Instead of telling us what she was like, the author shows us through Miyax's actions.  We can tell that Miyax is patiently observant and intelligent in the quick way she learns and remembers, and we also know that she is resourceful and self-reliant.  All of these traits are evident in the way Miyax seeks to survive with the wolves, intuitively using the concepts her father has taught her when she has to survive on her own.  Miyax is also pensive and has a deep affinity for nature, struggling to reconcile encroaching modernity and civilization with the old Eskimo ways she has been taught.  In evaluating and prioritizing her values in a changing world, Miyax shows a depth of character and a precocious maturity.

How is Miyax's appearance described in Julie of the Wolves?

Readers can get a solid physical description of Miyax in paragraph 8 of chapter 1. Much of this paragraph contains direct characterization, where the narrator gives us specific details about Miyax. We are told that Miyax is beautiful, and her frame is small-boned. Her muscles are strong and "delicately wired." She has black eyes, which means that her pupils are difficult to see, and her eyes slant. Readers get a little bit of narration that hints at natural selection and Darwinian evolution when we are told that the Arctic has sculpted life into compact shapes. Readers are told that Miyax is evidence of that phenotype when we are told that her arms and legs are short. Creatures with long limbs would lose too much body heat along those extended surfaces, so readers get the impression that Miyax is built for the frigid environment that she is a part of.

Unlike the long-limbed, long-bodied animals of the south that are cooled by dispensing heat on extended surfaces, all live things in the Arctic tend toward compactness, to conserve heat.

In the story, Miyax is described as a 'classic Eskimo beauty' with a round face, a flat nose, and slanting, black eyes. Her pale beauty is juxtaposed against that of the forbidding white plains of the tundra. Although she is 'delicately wired' and small-boned, Miyax's body is strong. Her compact build helps her conserve heat in the unforgiving Arctic environment.

When we meet her, she is on her stomach trying to get the attention of the leader of a wild pack of wolves. She is hungry and needs to eat, and the wolves seem to be her only way out. Inspired by the experience of her father, Kapugen, Miyax thinks that she can communicate with the wolves and that they will lead her to a food source before she starves to death.
