“The most fundamental element of balancing in a physical sense is finding some kind of ‘tripod’ for the rock to stand on.

How are balancing rock formed?
Balanced Rock is composed of Fountain Formation sandstone deposited along the edge of the Ancestral Rocky Mountains between 290 and 296 million years ago. Coarse sediments with sand and chunks of rock were swept off the mountains by quick-moving streams and rivers, which then deposited them in deltas and alluvial fans.
How does rock balancing work?
For stone balancing to work, it takes finding the right number of contact points and complementary surfaces. Most solid balance points are the result of two surfaces coming together, ideally one concave and one convex, so the two rocks essentially hug one another via 3 (minimum) contact points per balance point.
Why is rock balancing bad?
When stacking rocks it disturbs the natural order of nature. Every time you build a pile you’re basically scaring away wild animals and disrupting their natural habitat. Some experts argue that extensive rock stacking can even lead to extinction of certain species.
Why are cairns bad for the environment?
