Lawrence University junior Carly Roe was recognized for her research presentation on an unusual rock unit in central Wisconsin at the recent annual meeting of the Institute on Lake Superior Geology held in Thunder Bay, Ontario.

Roe, a geology and Russian studies major from Greenville, received second-place honors for her poster describing research on an unusual rock unit from the Baraboo area that is known only from drill cores taken in the early 20th century. Her research has implications for the oxidation state of the atmosphere in the geologic period following the initial appearance of limited amounts of free oxygen.

One of more than two-dozen student presenters at the annual conference, Roe received $100 as part of her award.

The Institute on Lake Superior Geology is a non-profit professional society that provides a forum for the exchange of geological ideas and scientific data and promoting better understanding of the geology of the Lake Superior region. Its annual meeting draws geologists from the United States, Canada and throughout the world.
