- •
Photogrammetry has opened the way for the use of virtual outcrops in geosciences.
- •
Photorealistic orthorectified cross-sections of outcrops can be generated.
- •
We applied this procedure to analyze fault growth on a barely accessible cliff.
- •
We compared results with trishear and flexural-slip extensional fault-related folding.
- •
Extensional fault-propagation produced a fold with coeval thickness variation.
