Some of the lava is not fragmented and flows from the vent as a lava flow.[5] Cinder cones are also called pyroclastic cones and are found in volcanic fields, on the flanks of shield volcanoes, stratovolcanoes and calderas.[6][7][8][9] For example, geologists have identified at least 30 young cinder cones on the Mount Edziza volcanic complex, a large shield volcano in northwestern British Columbia with an area of 1,000 square kilometres (390 sq mi).[6] Eve Cone, on the northern end of the Mount Edziza volcanic complex, is one of the best preserved cinder cones in Canada, due to its undeformed and symmetrical shape.[10] During other Hawaiian eruptions, fluid basaltic lava may pond in vents, craters, or broad depressions to produce lava lakes.
