Over time, erosion has carved this deep box canyon exposing its majestic bluffs. As you travel into the canyon, take notice of the stone steps. These were carved from the natural stone in the 1930s by the Civilian Conservation Corps. The stream that flows through Little Grand Canyon travels about one mile and drops 350 feet from the ridge top to the Big Muddy River. This stream is what remains of the powerful waters that carved these ridges and valleys for thousands of years. There are many places where soil has been washed away. Take a look around and be sure to keep your eye out for pioneer plants that are building soil on the bare sandstone. Many of the uprooted trees that you see along the trail are the aftermath of the Super Derecho that struck the southern Midwest in May 2009.
