At the mountains of madness

"The Cyclopean massiveness and giganticism of everything about us became curiously oppressive; and there was something vaguely but deeply unhuman in all the countours, dimensions, proportions, decorations, and the constructional nuances of the blasphemously archaic stonework. We soon realised from the carvings revealed that this monstrous city was many million years old."
Today's warmup, inspired by Lovecraft's mountains of madness
