Generate for me a description of a mossy forest scene with a boulder and a scarp.
assistant
During the centuries since the last tremor shook this great forest, giant oaks and fir have taken root atop an ancient northward-running fault. The scarp is partially obscured with vines growing from atop its face, but the tilted striations of colored earth are visible through the leaves. A moss-covered boulder, fallen from the rocky face, shelters a small cave.
