Hey, does anyone know who has or where I can get some good looking volcanoes. I've looked all over the forums and haven't found any. Thanks

Well there are several good terrain packs, all of which include volcanoes in the Conquests versions. Snoopy's, Rhye's, Warpstorm's (I think). Look in the graphics mods subforum, in any terrain pack thread.

I have been using these since C3C came out, does anyone know the author.

I don't think there was a separate thread, I think it was posted within someone else's thread.

they fit to vanilla style terrain?

I use them with Snoopy's standard terrain.
