Area’s Karst Geology is April 19 topic for monthly speaker series at Meehan Memorial Lansing Public Library

Thursday, April 19, the public is invited to celebrate Earth Day (a little early) by learning about the unique layers of rock that have formed over the past 500 years beneath the landscape of the local area. In a presentation entitled “Disappearing Streams: Karst Geology of the Driftless Area,” Dr. Kelvin Rudolfo will talk about the area’s karst geology, which is marked by sinkholes, springs and shallow soils, and also by a vulnerability to pollution.
