Maungawhau / Mount Eden forms the highest point in Auckland City. It has some of the best views over the city and is a prominant feature of the skyline. It erupted roughly 28,000 years through an earlier magma flow generated by Te Kōpuke. Like many of Auckland's scoria cones, it was subjected to various human interferences over the years: a resourvior is built into the northern side, the western side was quarried away, and various buildings have been constructed and since removed from the peak. Fortunately it is now under collective management by Auckland Council and local iwi to preserve it for future generations.
