What is Blake River Megacaldera Complex?
The '''Blake River Megacaldera Complex''' is a giant [[caldera]] cluster that spans across the [[Ontario]]-[[Quebec]] border in [[Canada]]. It is considered to be a [[supervolcano]] because of its great size (3,000&nbsp;km<sup>2</sup>) and its numerous [[dike (geology)|dike]]s and vents. The cluster is about 2700 million year old. ==Other websites== *[http://maps.google.ca/maps/ms?source=s_q&hl=en&geocode=&ie=UTF8&hq=blaker+river+loc:&radius=15000.000000&split=1&msa=0&ll=48.605674,-79.233398&spn=0.811803,2.381287&z=9&lci=com.panoramio.all&msid=110782344548492786994.00047285c024a9b679119 Google Map location] {{multistub|geo|Canada|science}} [[Category:Volcanoes of Canada]] [[Category:VEI-8 volcanoes]]
