How Fault Scarps Evolve into Faceted Spurs Through Erosion
Quick fact
A single fault scarp can be transformed into dozens of triangular faceted spurs as streams and rivers incise perpendicular to the fault, carving V-shaped valleys that isolate spur remnants within a few million years.
Why this is interesting
When a fault ruptures, it leaves a sharp, straight cliff—but over time, that clean face becomes a jagged series of triangles. How does a single, simple fault line turn into a row of faceted spurs?
