>>32662280River large enough to be marked on a map would have too much flow to seep into the ground, I would say. I can't think of a river system where something like that happens... Maybe a river flowing into a desert?
>>32662344Yeah, looks good. Also, honestly every jutting bit of elevation looks like a chode to me, but the good thing about the crater lake is that you don't need to give a shit about anything, it can be wherever you want. Just keep in mind that it is always very circular, and that if it has an island it will be in the middle.
