New at Rosetta Stones: Rainbow Fault Cake!

We all like creative ways to illustrate geological concepts. My supervisor brought in a cake that turned into a glorious demonstration of a dip-slip fault. Recipe included. Go check it out!

    Wow, the similarity between the cake and the rock formation was uncanny (unpackagey?), to say the least. But what a great colourful idea for a children’s cake! I’ll have to file it away for our next non-gluten-free birthday party (Eldest has a friend who, unfortunately, cannot partake of packaged cake mixes for medical reasons).

    Lovely! Unfortunately the second photo with the captions is getting clipped what should read “Hanging Wall” just reads “Hanging”.

    And speaking of hanging walls, I’m puzzled by the downward curvature. It seems like that end should get dragged upwards, somehow. Any help for a non-geologist? (I get it in the cake, where it’s been dragged down by the knife.)

    Trebuchet – Funny, I posted the same thing in the Rosetta Stones comment section. :-) So far as I can tell, yeah, drag folding should be bending the cake layers up rather than down, as illustrated in the article Dana linked:

    In the photo there, we have the same relative movement of the two chunks of rockage–left side up, right side down, and the stuff on the right side is bent upwards along the fault…
