Horizontal Corten Steel Branch Wall A 30ft long by 9ft high curved tangle of steel branches cuts through the landscape and hovers atop a shallow collecting pool. The pool is filled with pebbles in variegated shades of white. A curved burner for gas is hidden among the branches for day or night ignition. The surface of the pool may be either still and reflective, or undulate in endless ripples from a water agitator. The pool may also be designed so water cascades over hidden subgrade spill edges; giving the sound of rushing water from a hidden source.
