Episode description

Dr. Fred Calef of JPL talks to us about his work mapping the surface of Mars. He tells us about the non-linear path his life took that led him to the work he currently does, as well as the challenges of applying Earth-bound geologic concepts to other planets in our solar system, most significantly the red planet. This episode is part one of a two part episode with Dr. Calef.

We also break down our song "Geology Folk Song Medley" from out new album "The Fossil Record." If you're an earth scientist looking for that perfect campfire singalong, this is the song for you!
