The channels with boulders are clearly visible along the stretch from the sourthern powerline up to CO RD 25 along the river. There appears to be no ash layer at the outcrop.  The boundary here is represented by deposits laid down by a huge tsunami.


Description


Cretaceous–Paleogene boundary

The Cretaceous–Paleogene (K–Pg) extinction event[a] (also known as the Cretaceous–Tertiary (K–T) extinction)[b] was a sudden mass extinction of three-quarters of the plant and animal species on Earth,[2][3][4] approximately 66 million years ago.[3] With the exception of some ectothermic species such as sea turtles and crocodilians, no tetrapods weighing more than 25 kilograms (55 pounds) survived.[5] It marked the end of the Cretaceous Period, and with it the Mesozoic era, while heralding the beginning of the Cenozoic era, which continues to this day.
