I am making a cake for church and I wanted to do a mountain with the stream coming down any ideas or pictures? I don't want a normal tier cake. Please help

How funny, I've just had an enquiry about doing a mountain cake for a 50th birthday. My idea was to stack round cakes with 1-2in difference and carve them into a mountain shape and then cover with fondant (you could do BC too). That was until I just goggled for an image of Killamanjaro, which turns out to be kinda wide and squat!!! So I'm now puzzling over how I'm going to do that for 70 people, but the idea I had would definitely work for a regular mountain shape!

Check out my photos... I have a big green "moutain"or hill type cake...check it out...

Well depending on what size you want this mtn you could use a cupcake; giant cupcake; mini doll skirt; wondermold OR wonder mold w/an 8" round under it w/o having to carve any cake.

Otherwise, using your rounds 1" smaller on the way up you should do fine.
Only have 2" differences between pans.....start carving
