Nature
The Milbanke Sound Group is a cluster of five basaltic volcanoes on islands in British Columbia’s Coast Mountains, notable in Canada for rising from islands rather than the mainland. Likely formed within the last 10,000 years after the last glacial period, the cones are little understood and their most recent eruption is unknown. Mature forest now obscures many of their landforms. Kitasu Hill is the best preserved cone, while Helmet Peak is the highest and produced widespread volcanic deposits. Other smaller cones on Price and Dufferin islands and basaltic flows on Finngal Island show additional volcanic activity. Their geologic origin remains uncertain.
