the previous post, we see in this photo that the summer wood has collapsed, in this case, consistently to the right, and the winter wood is undeformed. The photo is a shot from the publication "Field Guide to Geologic Processes in Cascadia." This sample is not from the stumps in the five previous posts, but is a thin section of the permineralized charcoal from the Quartzville trip. The field location of the rock is reflected in the FlashEarth location, but the photo was actually taken in OSU's Radiation Center, where the thin section was made.
Photo unmodified. March 9, 2012. FlashEarth location.
