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
