An underground gorge

[industrygothica]

I'm designing a little 3 encounter for a group over at EN World, and want to make some nice little battlemats to go with it. I'll be importing them into maptools and then saving a screenshot to upload onto the forums.

The first encounter involved the party actually entering the cavern, and are conveniently sealed off by a cave-in. The only way out is a hop over this little gorge and to climb up the other side, which is significantly higher.

I'm sure the gorge could look better, but I'm happy with it nonetheless. I'm going for sort of a hand-drawn cartoony thing, so that's the reason for the bold outline. My problem is that for the life of me I can't seem to come up with anything else to put on this otherwise boring map. I guess maybe a big rock or two, or even some stalagmites, but I just don't know.

Then I'm making a second map, which will basically be the other side of the gorge. Hopefully I can make it look like it's going back down into a pit of sorts, where all sorts of nasties will be. The third encounter will take place on the same map, albeit from a higher altitude (well, at least the big red fire-breathing bad guy will be higher, but I won't tell you what that's going to be.. ). Any ideas for that one would help as well...

I know you guys won't let me leave here with too yucky of a map, so I'm looking forward to your input.
