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.
Visitors may walk from either of the two parking lots to the woodlands, the marsh, the fen and the prairie. There is a loop trail around Seigler Lake, with beautiful views over the water.

The preserve originated in 1992 with 294 acres. In 1998, 133 acres were added, which includes the gravel quarry. In 2003, 30 acres were added to the preserve. In 2006, 118 acres were added. In 2008, 19 acres were added. The final 246 acres that make-up the preserve were purchased in 2010, with partial funding through an Illinois Department of Natural Resources (IDNR) Open Space Land Acquisition & Development (OSLAD) acquisition grant.
Siegler Lake is a premier feature of the preserve. Formerly a limestone quarry, the lake was formed when high floodwaters breached the banks of Big Rock and Welch Creeks in 1996, sending torrents of water into the quarry. The result of this flood event was a 32-acre lake, complete with fish and invertebrates that were swept in with the floodwaters. Subsequent fish habitat projects have been undertaken, and the lake supports a diversity of fish and aquatic wildlife. It’s a popular destination for anglers.
