Why are these people posing and smiling?

Because they're being laser scanned. (Don't look at the flashing red lights!). Vince and Carolina, above, are having a bit of fun during a long-range laser scan by standing perfectly still, hoping to get incorporated, in a ghost-like fashion, into the final scan image. Not to worry, those things get eliminated during post-processing anyway. (Photo NDP)

Carolina, in the foreground, sweeps sand away from one of the fossil whale skeletons at Cerro Ballena, with Vince in the background setting up the FARO long-range laser scanner. The black and white squares and white spheres mounted to the posts surround the site are registration marks for the scanner. (Photo NDP)

Vince and Adam, in the bucket, affix one of the high-end cameras to the frontend loader in order to take a Gigapan view of the entire site. We are very, very excited to see the result of this work, which we hope will look something like a 360 degree eagle-eye view of this association of fossil baleen whales. (Photo NDP)
