Starved Rock State Park is a state park in Illinois, characterized by the many canyons within its 2360 acres.The Illinois River Valley in the Starved Rock area is a major contrast to the flatland. The valley was formed by a series of floods as glacial meltwater broke through moraines, sending torrents of water surging across the land and deeply eroding the sandstone and other sedimentary rocks. During early spring, when the end of winter thaw is occurring and rains are frequent, sparkling waterfalls are found at the heads of all 18 canyons, and vertical walls of moss-covered stone create a setting of natural geologic beauty uncommon in Illinois. Some of the longer-lasting waterfalls are found in French, LaSalle and St. Louis canyons. Waterfalls, rivers and streams can undercut a cliff, creating overhangs in the sandstone, like Council Overhang at the east end of the park. Other sights can be seen from the bluffs themselves, which provide vantage points for enjoying spectacular vistas. Experience the fun of outdoor adventure at Starved Rock State Park. Whether you enjoy hiking along the nature trails or viewing the many spectacular overlooks along the Illinois River, recreational opportunities abound. From picnicking to fishing to boating, from horseback riding to camping to enjoying winter sports, there’s so much to do that you’ll come back again and again ...and add to all of that ...stargazing!
