Rock cairns are human-made stacks of rocks. They take different forms and have been built by cultures around the world for many different purposes. Cairns may serve as monuments or navigational aids, among other uses. Placed along a trail, a cairn signifies that you are on the right track. It is a marker guiding you to the correct path or trail in cases where navigation becomes difficult, and the trail may be easily lost. The act of balancing stones carries with it a practice of patience and a physical effort of creating balance. Each rock can signify an intention of grace for thankfulness or offered up for another in need.

Cairns personify the purpose of GreenLight Balance which supports the mental health and wellness of users leveraging tools (the rocks) like screening, peer connections and community resources.
