Which symbol would you consult to identify a mine-related waste disposal site?

• A. Quarry
• B. Mill tailings
• C. Gravel pit
• D. Mean high water line

Answer: (B)

Understanding mine waste disposal starts with what tailings are: the leftover materials from processing ore, often kept in ponds or piles near the processing facility. A symbol for mill tailings points directly to where this waste is stored, so it identifies a mine-related waste disposal site. That connection to the waste produced by ore processing makes it the best indicator for such sites. A quarry marks a place where rock is quarried for construction, not where mine waste is stored. A gravel pit is another type of excavation for aggregates, not a waste disposal area tied to ore processing. The mean high water line indicates a shoreline reference and has nothing to do with mine waste locations.
