Auckland is quite a unique city geologically, being situated in the midst of a volcanic field. As a geology enthusiast, I find that non-erosion geological features are quite underrated on and off the World Heritage List, and this site is no exception. This is one of the youngest of these volcanic fields in the world, and therefore the most diverse range of volcanic features preserved, despite its location in a densely inhabited area. Indeed, a lot of scoria, a type of volcanic rock, was extracted and used in local architecture. During my 2013 trip to New Zealand, I visited Mt. Eden via the hop-on hop-off bus. Unfortunately, I hadn't reached the age of making the family itineraries and researching on destinations to know all this about Auckland when I had gone. I had, however, reached the age of rock-collecting, so Mt. Eden was one of my most vivid memories of Auckland, which was a bit forgettable after touring the rest of New Zealand. The peak rises over the city, which surrounds it closely on all sides. The rim, which is the only part accessible for tourists, is lined by road, from which one can look into the crater below. The whole mountain is made up of scoria, a volcanic stone with a pumice-like appearance but with more density. On the other hand, a great clear view of the whole metropolis reveals all the other, smaller volcanoes all around the area. In relativity, it's really quite a dense field with the unique setting of a flat isthmus, not to mention the city. The slopes, meanwhile, show the effects of Maori settlement, although it appears unclear what purpose the earthworks serve on first glance at the site, without research. While I'm not completely sure if it merits World Heritage status based on my visit, further research, helped by the first-hand impression, has drawn me to the conclusion that the site does have geological significance and impressiveness in diversity, and I think the cultural values simply strengthen the claim to OUV, a bit cultural landscape-esque, but it's that uniqueness as a diverse landscape that works for me.
