Beaver Creek Dendrite
Dendrites are a crystal or crystalline mass with a branching, tree-like structure.
Dendrites are branched or tree-life inclusions, usually of manganese or iron oxides that are caused by irreversible aggregation of small particles forming large clusters. The metals in the dirt stain the rock, in this case quartzite, in a random pattern (chaos and fractal geometry). LIke water pressed between two panes of glass. This pattern is a stain that is formed on the surface of the rock and when the seams are split open, the dendritic pattern becomes visible.
