Rainbow Falls, Manitou Springs, CO. This is Rainbow Falls in Manitou Springs, a small town west of Colorado Springs. It is hidden under a bridge that I've ridden my bike and driven across countless times in the past 25 years. Until yesterday I didn't know it existed! Since this water fall is in an urban setting the rock walls were covered with ugly graffiti. I had to photoshop most of it out. I think people who deface natural beauty like this are scum.
