This found on Deviant Art:

“Self-portrait.Basically, this is what I would look like when I came off of the dig every day the summer before last. It was crazy. I’d have more dirt on the floor of my shower than we’d actually moved on the site. Pretty sad. But it was a blast. I was burnt to a toasty crisp, run ragged, and if I had seen one more .25″ mesh screen or another goddamn Munsell chart at the end of that summer I would have killed someone. Probably one of my dig crew. And yes. Archaeology != Dinosaurs. Kthnx.”
