As you first approach Black Mountain, 25 km south-west of Cooktown in North Queensland, it looks like it has been burned in a bushfire. However, the dark colour comes from the immense jumbled pile of black, blocky boulders, some as big as houses, that cover the whole mountain (figure 1). The intact solid granite core is said to lie beneath the jumbled broken blocks. The boulder fields of Black Mountain National Park form an impressive and distinctive landscape of international geological significance.To read the rest, click on "Origin of Black Mountain, North Queensland, Australia". There are numerous links in the article for people who want to learn even more. The video below is supposed to start at about a minute and a half into it.
