38: Hidden Gems

This season's final arc is set in Greenland. Let's start with the most common rocks in the region: what are they and what stories do they tell about the world 3.9 billion years ago?

Along the way, we'll weave a tapestry of stone, boil some rocks, and learn a bit about Dylan's birthstone.

Extra credit: try the Play-Doh experiment from this episode, or make some stone soup.
