Hi folks! I've just been invited by my university to join a field trip to Iceland next week, one of the best spots in the world to study geology. This means there will be a slight hiccup in our programming.

Episode 38 will drop early next week, while Episode 39 will hopefully drop the first week of August. If I have time and space, I might try some experimental episodes from Iceland itself, field diaries and interviews, but no promises.

As always, thanks for your patience and support!

Why are some ancient rocks well-preserved, while others are extremely messed up?

Today, we'll take a side quest from our Greenland arc to learn more about metamorphosis, which changes rocks beneath our feet. On the way, we'll transform toast into cookies, take an elevator ride deep into the crust, and meet an ancient rock with a babyface.

Extra credit: make some toast, or go looking for butterflies.

What is the oldest *major* slice of rock, one that's relatively well-preserved, one that's fueled a half-century of research?

The episode's name kinda gives it away, but stay tuned as we meet the last location of Season 2: a series of rocks near Greenland's capital. Along the way, we'll meet the different groups of people who have settled on this remote island, and a geologist from the other side of the world. I'll also take a brief detour into why I unfortunately can't talk about every single ancient rock out there.

Extra Credit: Find a choir to sing in, or play some ping-pong.

How did the Man in the Moon form? What does the Moon's Far Side look like?

Today, we'll learn about the most visible remnant of the ancient world- the pattern of dark lunar rocks that stares down on us each night. On the way, we'll hitch a ride with a flying fax machine, play a game with crystals in magma, and learn why bananas are slightly radioactive (and why that doesn't really matter).

Extra Credit: Try to send me a fax, or just eat a banana.
