This picture shows a pathway that I hiked while going through Rock Creek Park. I took a lot of pictures while I was going through the area, however this one stood out to me because of the cleanliness of the path. Almost all of the other paths that i walked on had an abundance of tree roots or large rocks that scattered all over the pathway, however this path was relatively flat and clear. I started thinking about why that might be and I came to the conclusion that it was because it was one of the main paths in the area of the park that I was in. Having thousands of people walk, bike, or run over the same area of land would cause the soil and the rocks to be worn down over time. I have a feeling that there were no tree roots along the path to begin with because they would still be present on the pathway, but any larger rocks or branches could have been washed away by the rain, or even picked up and tossed aside by travelers. I thought it was really interesting though to encounter a path that was not concrete that was so smooth and easy to walk on because most of the other trails are covered with obstacles that one has to maneuver around.
