The sun shines above a frozen column waterfall in Ottawa Canyon at Starved Rock State Park on Monday Jan. 10, 2022. Icefalls are forming in nearly every canon in the park. Park staff recommends to be prepared for extremely icy staircases, trails, and canyons if you decide to visit Starved Rock and Matthiessen State Park. Proper footwear with clip ons such as Yak trax and ski poles or hiking sticks will help with balance. (Scott Anderson)
