Day 32 (July 27, 2011): Bernie and the Diatoms
July 27, 2011
Once upon a time, this arid and dusty terrain was once the home of an ancient lake. Observations of the sediments show that water once filled the Olorgesailie basin. The paleo-lake was a major hotspot, attractive to wildlife and hominins. Therefore, reconstructing the lake and its environment is paramount in our understanding of the life that once lived here.
Actually, we should use the plural ‘environments’ because the lake changed considerably over its history. The person who has helped us understand this visited camp today. Bernie Owen is an old friend to our project, and he’s spent many summers with us at Olorgesailie as our diatom specialist. He was joined by colleagues Robin Renaut, Tim Lowenstein, and a graduate student Ginette Felske.
