What does the orange diamond with crossing lines Non-Lateral Marker indicate?

The orange diamond with crossing lines, known as a Non-Lateral Marker, indicates a navigational hazard that is not related to the lateral (side) navigation of waterways. It serves to alert mariners to areas that may require caution, such as obstructions, construction zones, or other obstacles that could pose a danger to navigation. These markers do not indicate the sides of a navigable channel like lateral markers do, but rather provide important safety information.
