Not quite a geomorph

Sat down this morning at Peet's intending to work on my submission for Dyson's map contest, but ended up drawing this instead.  Drawn on Strathmore 4" by 4" watercolor Artist Tile so it is square, but I didn't try to match up entrances with extant geomorph patterns or even each other. It could be used between geomorph map areas as a pattern breaker or at the edge of one.

By the way, the tile is very heavy paper, so drawing on these could make for really sturdy physical geomorphs.
