CT scan and photo of a sediment core from a lake

Detailed Description

Images of a sediment core taken from Floras Lake, a coastal lake in southern Oregon. Top image is a false color computed tomography (CT) scan, and below it is an actual photograph of the core. In both the CT scan and the photograph, the lighter, brighter colors are dense sand and the darker colors are mud layers. Scientists use the CT scan in order to see unique aspects of the layers of sediment that may otherwise not be visible.
