Hoodoos, oolites and sills, oh my!

Now studying sedimentary rocks, stuff that breaks down and then gets stuck together again. Love those hoodoos and arches that form in the desert. Is that magical or what. And oolites, little pearls of silt that get plastered into, what else, oolitic limestone. And great formations like dikes and sills, rocks that are denser and get left behind by the rain and wind. My, this is quite a dynamic system, this little blue ball whirling through space. And I am beginning to get it. This is my favorite time of the semester, about a third into it, where the lights go on for me. I see that I can do this, understand and remember and prove it on tests (got 100% on the last quiz!). It has gotten easier as I go along, so those gray cells are getting super-charged again. Miracles happen.
