The most volumetric and “heaviest” of the five forms, Plato associated the icosahedron with the element of water. It is comprised of twenty equilateral triangles, meeting at twelve vertices which form pentagonal connections. Its geometry is mathematically related to that of the dodecahedron and both are derived from the golden ratio.



The icosahedron was associated with water and is located here in a lush bed of low-growing balsam fir, in reference to the cycling of water by trees in this dense, wet, biodiverse forest environment.
