Yesterday afternoon I hiked a short distance to the Verde River and built a pool by stacking rocks until the water was a few feet deep. I sat in the beautiful whirlpool and built several Cairn while listening to the sound of the rushing water around me. When I got home, I made several Cairns out of beach rocks I picked up in California and it made me think of what these little stacks of rocks are intended for. When someone has traversed an uncharted path, and found the way, a Cairn can be created so the next traveler can easily follow. It is a great testament to humanity to see these little rock sculptures placed in critical spots along the rugged terrain to help guide their fellow travelers who happen down the same path.
