Touch-Up: William A. Lunk, associate curator of exhibits at the University's Exhibit Museum, touches up a display in the mineralogy room showing the changes in prehistoric seas in Michigan and their effect on the state's minerals. Lunk designed and executed the exhibit, including the three-dimensional maps at left and right. Each map was made of plaster with wax contours carefully modeled and painted and topped with a grid of threads to represent latitude and longitude lines. Each took about 10 days to make.
