News from the Field: Day 4--The Bishop Tuff eruption

Another great breakfast at WMRS, and off to begin our exploration of the Long Valley Caldera and the cataclysmic Bishop Tuff eruption--one of the greatest volcanic events of geological history. We started with a stop at the Bishop pumice quarry for a close-up look at the airborne deposits of the great eruption, and gradually worked our way closer to the center of the caldera. We then explored an unusual set of deformed lake sediments at Chalk Bluffs, followed by a couple of hours exploring the magnificent exposure of the Bishop Tuff along the Owens River gorge. At the end of the day, we drove to our to our new home, the Sierra Nevada Aquatic Research Lab, better known as SNARL--and a magnificent dinner prepared by our chef, Linda Dore. We spent the evening hanging out in our new home--with a new writing assignment.
