The big picture: A lithospheric cross section of the North American continent

EOS Researchers [R.Clowes, P.Hammer] have constructed a lithospheric cross section that spans the continent and extends down to the base of the North American tectonic plate (up to 270 km depth). The 6000-km-long corridor across southern Canada and its margins illuminates the assembly of the North American continent at an unprecedented scale. See GSA Today(poster) and UBC-Science.
