As We Walk Through Fields of Lava

June 6th, 2012

FILLMORE, UTAH – Whitney and Matt took charge today, leading us on an investigation of the lava flows that extend westward from the Miter cinder cone.

The view of Miter from its lava fields. A tiny reflective spec at its base on the right side of the photo is our van, for scale.

We picked our way across the sharp, rubbly flow surface and learned the importance of careful observation. Although we weren’t looking for bombs and xenoliths, we found both along our path.

A volcanic bomb that has been rafted or carried away from the cone by the lava flow.

Whitney had a successful day of mapping the margins and morphology of a couple of complicated lava flows.

Whitney stands on the boundary between an older, vegetated lava flow on the right and a younger, black lava flow on the left.

Matt’s productive day included finding a spectacular fault exposure, where he made lots of measurements on the fault and associated joints.

Kevin poses at the most significant fault locality, where some of the surfaces display plumose structures for joints and striae for fault motion.

Overall, it was a strong start to the field project, despite the searing sun and blinding wind storm.

A perfectly nice day in the field (if you don't mind winds that will make your hair stand straight out).

We were rewarded for all of our hard work.

For one, we made a new friend.

We also found petroglyphs that showed these radiating straight lines.

The petroglyphs also showed a hand print.

The best reward was the home-cooked meal that we were treated to by Ms. Huntsman, complete with pie.

We hope every day of our field season is just like this one (minus the wind).

    Great seeing my Aunt Sylvia, and that beautiful collared lizard, and the petroglyphs, and Whitney’s hair in the wind, and those volcanic bombs, and even those joints and faults! Such a cool expedition.
