A class at Lac Courte Oreilles Ojibwe University recently discovered evidence of creatures that once thrived along an ancient seashore half a billion years ago in northern Wisconsin. Mike Heim, the university's natural sciences professor, takes students in his Earth Science class on field trips every fall to visit geological formations. They range from 1.7 billion years old to glacial deposits left behind about 12,500 years ago. In October, the class visited the Mount Simon sandstone formation which extends along the Upper Mississippi Valley and southern Great Lakes area and dates back more than 500 million years to the Cambrian Period.
