The Shawnee landscape took millions of years to form the Garden of the Gods in Southern Illinois. Long ago most of Illinois, western Indiana and western Kentucky were covered by a giant inland sea. Millions of years ago, great rivers carried sand and mud to this inland sea where it settled along the shoreline. Over time, the enormous weight of the sediments turned them into layers of rock, thousands of feet thick. At the Garden of the Gods, the sediment layers averaged over 20,000 feet thick or about 4 miles deep.
Ultimately, a great uplift occurred raising the inland sea above sea level causing it to fill in with sand and mud. The uplift also fissured the bedrock uncovering it to erosion including windblown sand, rain, freezing-thaw actions, which wore down the layers of sediment creating the stunning rock formations at Garden of the Gods.
This place was so beautiful with its large boulders that looked like rock stacked art. You can also learn about what happens when an unstoppable object meets an unmovable object..
They call the tall stack to the left ‘Devil’s Smokestack’. To help with scale, there is a human on the top of the ridge to the top right.
The colors are magnificent! So many minerals, so much mixing. Looks like nail art to me! 😉
I love these steps.
