I really like the Strata and Outcrops shader but it lacks any DRE or Differential Resistant Erosion, so I came up with this function to be applied to it, or just a stoneface.

It's actually a pretty simple setup. Voronoi noise stretched out to give intersection channeling (resistant) and Differential (face angle erosion) looks.
