Have you found claws and fangs during your travels? Did you know that you can exchange them for useful items?
Wolf fangs and bear claws are highly valued by the Native Americans. Go to their tribe and find Anakvad, a friendly trader. He has lots of useful resources for an exchange!
To visit the Native American tribe, make sure to clear the Snowy pass first! Make sure your character has at least 5 Warmth points, bring up some pickaxes with you, and prepare to dig your way to the North!
