What best describes the term 'Gravel, sand, clay or borrow pit' in the symbol set?

• A. A cave entrance feature.
• B. A type of vegetation boundary.
• C. A mining-related deposit pit depicted as a Mines and Caves symbol.
• D. A surface water feature.

Answer: (C)

Gravel, sand, clay or borrow pit refers to a place where construction materials are dug out, a surface deposit pit used for mining materials. In the symbol set that includes Mines and Caves features, this kind of pit is treated as a mining-related deposit pit and is depicted with the Mines and Caves symbol. It isn’t a cave entrance, a vegetation boundary, or a surface water feature, so the best fit is the mining-related deposit pit shown by that symbol.
