This cake was over 2 feet tall, and sat on a 2 feet by 1.5 fit wooden base.

The rock formation on top is rice crispies, but the rest of the mountain is cake. Dusty Crophopper, the plane on top, is styro and foam core covered with fondant.

The flames are melted candies with twinkling lights behind to look like flickering fire. The cake also had four receptacles embedded in the cake to hold water and dry ice for smoke.

There is a full structure explanation with a few progress shots on my Facebook Page.
