A gravel pit is an open-pit mine for extracting gravel. Gravel pits often lie in river valleys with a high water table, naturally filling with water to form ponds or lakes. Old, abandoned gravel pits are used for various purposes such as nature reserves, amenity areas, landfills, and recreational activities.
In Germany, former gravel pits filled with water are known as "power dug lakes" and are used for recreation. Many UK gravel pits also serve as fishing spots due to the presence of freshwater fish like carp. Gravel and sand extracted from these pits are primarily used in construction.
Gravel pits cannot be compared to real mines in terms of mineral, fossil, and gem content. Mines typically have extensive underground tunnels and spaces with a more significant variety of specimens. Municipalities often require permits to regulate gravel pit mining activities and disposal practices.
If not filled with water, mining companies or communities may rehabilitate gravel pits by planting grass and trees onsite. Gravel pits are typically located close to the earth’s surface and result from weathering and erosion processes.
