NATURAL HAZARDS OF STARVED ROCK STATE PARK

One wouldn’t expect the need for a hazard-assessment study in Illinois, but Starved Rock State Park defies this misconception. Set along the scenic Illinois River, the park boasts 18 waterfalls and as many sandstone canyons, carved by streams tributary to the Illinois River since the Kankakee Torrent thousands of years ago. Beautiful as this scene is, there are many hazards throughout the park. This research identifies natural hazards and pinpoints areas with the highest incidence rates of injury and death. Hopefully, additional safety measures can be put in place to inform the public of such dangers.

These geologic hazards have been identified: steep canyon walls, flood events, loose or unconsolidated rock, and rock falls. Potential hazards that have not yet been recorded in any incidents include landslides and slumps and falls near or into abandoned coal mines [there are many old coal mines within the park's boundaries (Myers 2007).] Other hazards include falling tree branches, uneven and overgrown trails, and slippery, ice covered paths in the winter.

During the five and a half year period from January 1, 2008 through August 31, 2013, 16 people fell into a canyon or fell from high places like Eagle Cliff or Lover’s Leap. Another eight people injured themselves while hiking or climbing in or close to canyons; one of the eight was injured by a rock falling on their head in St. Louis Canyon. French Canyon has the highest incident rate of injuries; this is the closest canyon to the visitor’s center and is the easiest to hike to.

In general, accidents occur most often from people tripping and injuring themselves on uneven trails. Falls into canyons are the second most common accident. On the opposite side of the spectrum, no one has yet to fall into an abandoned coal mine shaft or has been injured or trapped in a landslide.

Hazards are present in Starved Rock State Park. This study of the geologic history and hazards in the area, plus circumstances surrounding accidents, should assist visitors in avoiding dangerous locations and situations.
