Make a concise location description of a spooky sand dune in the wilderness with tar-like sap and plants.

Strangely, this region of the sandpit is marked with black weeds sticking above the surface and clinging to the rocky walls. An oozing, tar-like sap coats the plants, already corrupt in appearance, and gives them both shiny and sticky qualities. Despite the vile goo corrupting the pit, the sands continue to swirl all around.
