The Geological Story of Coffee Creek Preserve
Like much of the region, Coffee Creek’s story begins with glaciers. As the glacial ice sheets receded some 18,000 years ago, they left behind a rich and varied mixture of clay, sand, gravel, and even boulders. Today the creek is fed not only by seasonal precipitation but also by groundwater flowing from the high ridges of the Valparaiso moraine, another legacy of the glaciers.
Because so many insects thrive in the creek, it’s also a great spot for crawdads! These fierce-looking freshwater crustaceans are quite shy, and will swim backwards when approached.
What to Expect
Street parking is available in front of the Preserve. A small parking lot is also available off Sidewalk Road, to the north. Restrooms are available near the Pavilion.
Visitors must stay on designated trails at all times. We have created a video to help you learn about your role in enjoying the dunes area safely while minimizing your impact on the park.
