The Dungeoneer's Survival Guide is a gift that keeps on giving as far as maps go. There is a whole wealth of interior artwork (not counting the maps themselves) that inspire geomorphs with interesting terrain. The following piece looks like a great place to stage a subterranean action sequence. Imagine a party of adventurers having to hurry over that rough terrain while roped together.
The geomorph based on this illustration assumes a cavern full of crevices and other impassable terrain. Only a series of ledges (often abutting natural columns) will allow a party of careful adventures to make their way across the southern part of the tile. Rounding things out in the north, we have two passages that cross over each other.
