Presence of spirals with unit cell dimension step height has been established over a large variety of materials. But often spirals with large step height are also being reported. In this paper such a macrospiral observed over the barium based flux grown YAG crystals is reported. Nature of this depressed spiral and growth conditions are discussed. A possible formation mechanism is suggested for the development of spiral with large step height of giant step, which is termed as macrospiral.
