On Tuesday August 18th Rooms 10 and 8 visited Mangere Mountain. We learned so many interesting facts about the volcano and other volcanoes in the Auckland volcanic field. We learned that Pigeon Mountain is the oldest and Rangitoto is the youngest at around 600 years old! We saw different types of volcanic rocks such as Basalt and Scoria as well as examples of rocks formed from the lava bombs. There are the Spindle bomb, Lens, Breadcrust and Cowpat!! Did you know that Mangere Mountain is special because it is the only Auckland volcano to have a Tholoid- (a dome shaped plug formed after the magma gas chamber runs out of gas)? It was a great trip.
