It's a big thumbs-up, of course...

If you include the "cliff face" you'll see it's a six-fingered left hand giving a big thumbs-up. Perhaps an ancient, eroded advertisement for something. Or the entrance of an underground gladiatorial arena. Either are more likely than any sort of woman standing in the freezing cold flashing her ta-tas.

Obvious icon!
