Purdue University Northwest (PNW), in partnership with the Coffee Creek Watershed Nature Preserve and the Nature Conservancy, will host a spring nature walk from 10 a.m. to noon, this Saturday, at the Coffee Creek Watershed Nature Preserve in Chesterton. PNW Professor of Biology Young Choi will lead the nature walk and provide an opportunity for participants to learn about the wildflowers, trees, natural history, and ecology of Coffee Creek, the Little Calumet River, and Lake Michigan watershed in Northwest Indiana. The walk is open to the public and free of charge with funding provided by the National Oceanic and Atmospheric Administration and the Indiana Department of Natural Resources. No prior reservations are required but participants are asked to register at the preserve’s pavilion on the day of the workshop. The pavilion is located near the Sidewalk Road (CR1050N) parking lot. In the event of rain, the workshop will take place at 1 p.m., Sunday, May 6th.
