In this field geology activity, students will explore basaltic lava flows along the shoreline of Lake Superior, and begin to gain an understanding of the geologic story of Minnesota's North Shore. They will make observations about features seen in the flows and determine where they are likely to occur in a lava flow by making a drawing of a lava flow from top to bottom including the features they discovered in the field. They will correlate the features they observe with the shape of the shoreline looking for the geologic story of this beach.
