On April 5, volunteers from the Friends of the Lakeshore Nature Preserve will offer a Destination for Exploration as part of the three-day UW-Madison Science Expeditions. Friendly guides will greet visitors at the entrance to Picnic Point (2000 University Bay Drive), and direct them to three exploration stations. At the rock wall, Emeritus Geology Professor Dave Mickelson, and Science Olympiad coach Scot Moss will introduce the rocks that make up the wall and talk about their surprising origins. At the tree station, naturalist Diane Dempsey will help visitors identify trees (without their leaves!) and calculate tree age. A birding station hosted by naturalists Paul Noeldner and Chuck Keleny will include binoculars and a spotting scope for looking into the spring sky and across the lake, and strategies for identifying birds. Kids and families are welcome.
