13x9 cake for bottom layer. Cut a 9" round into pieces for top two layers. Graham crackers for the tent. Candles and pretzel sticks for the fire. River/waterfall was made by putting a layer of buttercream down first. Then piping gel on top. Used the "Piping Gel Recipe that Works" recipe. (easy for a beginner to follow and make) Rocks are chopped black walnuts. Not beautiful like the pros make, but my 4 year old son squeeled in delight. Priceless to me.
