Abstract
Abstract A portable campfire fireplace for containing a campfire and for providing a cooking surface which is adjustable with respect to the fire, in which side walls form a firebox and are hinged to fold flat, side by side. A post extends upwardly from eyes at one corner of the firebox and a bracket for holding a grill is slidable and rotatable on the post. A collar and set screw hold the bracket in place on the post. All pieces of the fireplace can be attached to one wall of the firebox for storing and transporting the fireplace. A false bottom may be disposed in the firebox for charcoal cooking, to hold the charcoal near the top of the firebox.
