Hang Son Doong cave in Vietnam is the largest cave in the world. Discovered in 1991 by Ho-Khanh, it wasn't until 2009 when British scientists surveyed it that its massive size was known. One of its caverns could fit an entire New York City block and it holds a river and jungle inside. National Geographic documented the cave in 2010, revealing its chambers that are over 5 km long, 200m high, and 150m wide, making it twice the size of the previous largest cave.
This document provides information about Canada including its area, coastlines, capital, and music. It then lists various landmarks and natural features from across Canada such as Parliament in Ottawa, CN Tower in Toronto, Chateau Frontenac in Quebec City, Lake Louise, Maligne Canyon, and Hoodoos in Alberta. The document concludes by stating the pictures are from Tuna's archive.
