One of Northeast Iowa's gems is the State Preserve known as Brush Creek Canyon. Each trip I make here is filled with wonder! If you have not yet been here, add it to your bucket list.
Some describe this area as a "rock city" which comes from the fact that the dolomite bedrock of the area has slumped off the main and gravity is calling it downward. The slumped pieces make a very slow journey and as they "travel" they have left a meandering maze of passageways between them. People of all ages enjoy exploring the surfaces, the spaces between and the enormity of the cliffs.
In one of my first explorations of the area I discovered a walk through cavern or cave. It has since become an EarthCache for those that participate in geocaching to discover. To learn more visit www.tinyurl.com/brushcreekcanyonEC. Climbing this terrain will entertain children for hours!
The path will eventually take you to Brush Creek. In much of the year it is possible to wade through. Take the stream down through the first and second bends for great views of the dolomite outcroppings. Check among the rocks in the stream for crawdads or just generally cool off as you soak in the amazing beauty around you.
