(updated January 24, 2014 per Mark Mcconnaughhay, Superintendent /Starved Rock State Park)
Ice falls have formed in the several of the canyons at Starved Rock State Park. Winter is the only time when climbing is allowed at Starved Rock, where the sandstone is fragile and dangerous. All climbers must register at the park maintenance building and should call the park office ahead of time, (815) 667-4726. Some rules and park instructions have changed. The four canyons where ice climbing is allowed (when conditions are right) are: Ottawa, LaSalle, Tonty and Wildcat.
Climbers are responsible for determining whether an ice fall is safe to climb. Climbers participate in climbing at their own risk.
Hiking in winter, likewise, is an at-your-own-risk scenario. Mark McConnaughhay, Park Superintendent, said the park staff spends a lot of its winter hours on snow removal on roads and parking lots, but not on the trails. They also spend much of the winter repairing equipment and preparing for spring and summer.
