All are welcome to join us for our Spring EcoWalk at Big Rock Forest Preserve on Jericho Road in Big Rock. This fully accessible, intergenerational event will be held from 9:00 am to 11:00 am. We will meet in the first, main parking lot off Jericho Road.

Mature woodlands, high-quality marshes, tall-grass prairie, clear-running creeks, and a 65-foot-deep lake are just some of the highlights of Big Rock Forest Preserve. Big Rock Creek, rated one of the best quality streams in Illinois, is home to freshwater mussels — indicators of high-quality habitat. High sandy bluffs overlook patches of woodlands and prairies in the preserve, and a specialized wetland called a fen is fed by underground seeps on the southeastern portion of the preserve. The FVPC EcoWalk will visit in the spring and hope to hear some frogs and toads calling.
