foreground geology for coal generating plant area

Here are some shots of the adjoining mountain range and the tail end of the California Zephyr.
After applying rock castings, I blended them together with Fiber Decor and Plaster. I will need to build the
adjoining scenery and then cut the two parts at the seam to insert a rip cord within that seam. The seam will be
finely patched and painted to be unseen.
