A buoy that marks the hazard of rocks is typically a "cardinal buoy," specifically one that indicates the presence of hazards on the cardinal points of the compass. These buoys are often black and yellow, with specific patterns that signify the direction of safe passage. For instance, a north cardinal buoy has two upward-pointing triangles, indicating that mariners should pass to the south of the buoy. Additionally, cautionary "hazard buoys" may also be used, which are usually colored orange and may display warning symbols.
