We are back in Germany – green, rainy, well-organised, toilet paper deprived Germany – oh how we missed you, or did we?! I`ll admit it dealing with the thought that we might not be able to get back was pretty unpleasant, but I can`t say that I felt particularly homesick over the last two weeks and I hope neither did the other fieldtrippers.

Where else can you go for a walk on the so-called “Moho“? A boundary layer that marks the transition from the Earth’s crust to the Earth’s mantle and that usually lies several kilometres deep inside the Earth?
