Using my geology noodle tonight...
Dating of layers came up in conversation tonight, so I pulled up an image of a cross-section to show Michael how it works. That led to a nifty online quiz designed for some geology class in New York. Unfortunately I couldn't get it to calculate my score (probably not compatible with my browser). But I think I did all right! Had to guess on a few questions though, because I sure don't know the geology of New York state!
Either way, it was fun little mind exercise and I thoroughly enjoyed it. I also think I should take that cross-section picture above and embroider it somewhere. That would be very cool.
I love rocks. They have such a solid permanence about them, even though they are ever-changing. The change is just so miniscule and most often not obvious to our crude sense of sight and time. I like knowing that they can be relied on to be there, yet could possibly blow at any time!!!
