Tsunami deposit (dark band) - 201306

Selected for Google Maps and Google Earth

_JAY4048-51 The buried plants and tsunami deposits make this perhaps the best documented example of tsunami deposits older than Pleistocene! Look at THIS PHOTO for a close-up view of the structure. The above photo was taken after several days of drying so the clay of the ancient marshland is cracking and flaking unlike the other photo taken on a damp day.

Is it those dark sparks? Interesting things!

It is the dark layer angled down from about the middle of the photo on the left.

Very cool Larry - how is it identified and what is the age?

The layer is a uniform sandy matrix. Reeds were growing in the marsh below the tsunami layer and also in the mud above. The layer is uniform and does not very in thickness in the section measured. I believe this section is about three million years old. More study is planned and a paper should be published on this in the near future.
