Long before there was a Lake Superior, this region was a dramatic landscape of fiery volcanic eruptions and huge lava flows. Join University of Minnesota Professor Emeritus John Green for this two-day course that combines indoor background sessions with field trips along the North Shore. Examine the rocky evidence of this dramatic volcanic history and how geologic processes have shaped our wonderful scenery and influenced the bird and wildflower populations. John has spent many years exploring and mapping the geology of the North Shore, introducing hundreds to the fascinating story it has to tell.
