Spent a third straight weekend with students and fellow geologists in the field. I was pleased with the telephoto that allowed me to get an angle on a relatively inaccessible outcrop. I know I could just explain it, but so many of you seem to enjoy the challenge, so...what's going on here?
Happy Easter, and a good spring-time to you all!
Update: Ron is absolutely right about the columnar jointing. What kind of volcanic rock, and why is the rock forming a flat-topped ridge?
