And we're back.
Cerro Ballena as it looks today. In 2011, the scene was littered with fossil whales, everywhere. This is new blacktop, on the northbound lane that didn't exist in 2011. (Photo: H. Little).
Over this weekend, Holly Little worked with our Chilean counterparts to successfully capture a photogrammetry dataset of Cerro Ballena. Why? With the right tools and techniques, we can create a 3D point could of the entire site from a carefully collected sequence of 2D images -- taken with scale bars, precise lens and camera settings, and bit of an artist's eye. What we hope to do is create a precise and accurate 3D model of the entire roadcut as it is now, in 2013, with the northbound lane in place, running through the same quarry where many dozens of fossil whales were collected.

In the end, we hope that by layering our different datasets, we can enhance the narrative of our work at this site, what we found, and how we tell the story of its origin. More to come when we start digging into the dataset, but Holly's GoPro snap, below, shows the action firsthand. Great work and a big thanks to the UChile team for the help!
