When traveling along an Interstate in hills or mountain country, notice the cutaways in hillsides made by the highway construction crews. Exposed bores from drilling (for placing dynamite) reveal the rock strata which often shows a pattern of "rock flow" set at an angle - close to 22 degrees, which shows the uplift of rock when our planet was young and convulsing. That eons-old pattern can be carved into Sculptamold and then painted as layers of strata like a sedimentary rock formation.
Volcanic rock formations are a different category, but there is a "flow pattern." My Earth Science teacher called those rocks a product of "igneous fusion" from volcanic activity.
The scenery on your layout could make a visiting geologist excited.

I know exactly what you're speaking to. I see many rock formations along the interstate that seem to have moved along a slope as the magma blended. And I have often thought of using wire to somehow re-create the bores from blasting that are still visible.
Ok, I'm getting way ahead of myself.
