I've taken the plunge.
I just sent off my first four pages of entries to the Community Geomorph Project.
For those not in the know, Richard over at Save Vs. Dragon and the creator of the d30 DM Companion was inspired to begin a Geomorph project among the d30/OSR/RPG community. I was intrigued and decided to spend a day laying some lead down onto paper.
For the most part, I'm pleased with the results so far. It's a lot of fun to throw these small rooms/areas together without worrying about what "the whole" looks like. I've varied between caverns, temples, corridors, and single rooms. Lakes, ramps, chasms, and balconies are all found therein.
Ultimately the goal is to compile all of the community-generated geomorphs into one large PDF. They may also be thrown onto Dave's Mapper as well.
I'd urge you to check it out if you haven't already. It's for a worthy cause, after all...because you can never have too many maps!
Here are my first offerings:
