Sulfur (Inventory)/Crust
From LagWiki
The Crust field of the Sulfur section is used to record any appearance of a sulfur crust.
Sulfur crusts tend to be strongly associated with gypsum and may overlay or be mixed with gypsum crusts. Sulfur crusts appear as yellow, crusty deposits that are not tightly adhered to the underlying substructure. The thickness and color can vary. These crusts may appear high in a passage, near the ceiling but could appear almost anywhere. Look for them if indications of gypsum are present or especially if other sulfur formations are found in the area.
