Chicxulub impactor Chicxulub impactor The Chicxulub impactor ( ), also known as the K/Pg impactor and (more speculatively) as the Chicxulub asteroid, was an asteroid or other celestial body some in diameter which struck the Earth at the end of the Cretaceous period, approximately 66 million years ago, creating the Chicxulub crater. It impacted a few miles from the present-day town of Chicxulub in Mexico, after which the impactor and its crater are named. Because the estimated date of the object's impact and the Cretaceous–Paleogene boundary (K–Pg boundary) coincide, there is a scientific consensus that its impact was the Cretaceous–Paleogene extinction event
Kauhakō Crater the surface of the lake and lifeforms, including shrimp and plankton, to disappear. Kauhakō Crater is thought to have formed around 230,000 to 300,000 years ago. Somewhere within this time period, Pu'u 'Uao, an undersea volcano located near what is now the peninsula, first erupted. After this, it continued to erupt several more times, spewing hot, fast lava. When this lava eventually cooled, the peninsula was formed, including Kauhakō Crater. Kauhakō Crater is found in the center of the Kalaupapa Peninsula. It is located inside a volcanic rim, which is roughly above sea level, making it the highest point on
