A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to manage their safety risks and reduce their environmental impact.[1][2]
Many quarry stones such as marble, granite, limestone, and sandstone are cut into larger slabs and removed from the quarry. The surfaces are polished and finished with varying degrees of sheen or luster. Polished slabs are often cut into tiles or countertops and installed in many kinds of residential and commercial properties. Natural stone quarried from the earth is often considered a luxury and tends to be a highly durable surface, thus highly desirable.
Quarries in level areas with shallow groundwater or which are located close to surface water often have engineering problems with drainage. Generally the water is removed by pumping while the quarry is operational, but for high inflows more complex approaches may be required. For example, the Coquina quarry is excavated to more than 60 feet (18 m) below sea level.
To reduce surface leakage, a moat lined with clay was constructed around the entire quarry. Groundwater entering the pit is pumped up into the moat. As a quarry becomes deeper, water inflows generally increase and it also becomes more expensive to lift the water higher during removal; this can become the limiting factor in quarry depth. Some water-filled quarries are worked from beneath the water, by dredging.
Many people and municipalities consider quarries to be eyesores and require various abatement methods to address problems with noise, dust, and appearance. One of the more effective and famous examples of successful quarry restoration is Butchart Gardens in Victoria, British Columbia, Canada.[4]
Water-filled quarries can be very deep, often 50 ft (15 m) or more, and surprisingly cold, so swimming in quarry lakes is generally not recommended. Unexpectedly cold water can cause a swimmer's muscles to suddenly weaken; it can also cause shock and even hypothermia.[5] Though quarry water is often very clear, submerged quarry stones, abandoned equipment, dead animals and strong currents make diving into these quarries extremely dangerous. Several people drown in quarries each year.[6][7] However, many inactive quarries are converted into safe swimming sites.[8][9]

From Mission Blvd (Hwy. 238) in Fremont, turn south on Nursery Ave. (away from the hills) and right (west) on Niles Blvd. Turn left on Osprey Drive and left on Quarry Lakes Drive. Proceed to the park entrance on the left.
A beach wheelchair, intended to provide a means for wheelchair users to travel across the beach, is available free of charge on a first-come, first-served basis at the swim complex. They require an assistant to push and are not intended to enter the water. To arrange for use of the beach wheelchair contact the Lifeguards at (510) 690-6629 or the Park Rangers at (510) 544-3133. Arrangements will be made to bring the chair out to the beach. It takes approximately 15 minutes to prepare the chair. Staff will give a brief orientation to the chair and arrange a time for the chair to be returned.
There is a wheelchair accessible fishing pier at Horseshoe Lake. All the facilities at the Niles beach area, the Ensenada Pavilion area, and the Orchard picnic area are wheelchair accessible. The Rock picnic area has wheelchair accessible bathrooms and a drinking fountain but no parking.
History is everywhere in the area of Quarry Lakes Regional Recreation Area in Fremont. Native Americans inhabited the region for millennia before the arrival of Europeans, notably in the sites that are now preserved at Coyote Hills Regional Park west of Quarry Lakes.
Quarry Lakes incorporates the historic boundaries of two Mexican ranchos and the former Mission San Jose lands. Alameda Creek was the original boundary between Contra Costa and Santa Clara Counties. Alameda County was carved out of these two counties in 1853 and was named after the creek that drains it.
The quarries for which Quarry Lakes Regional Recreation Area is named were established in the mid-19th century. Gravel taken from the banks of Alameda Creek was used in the construction of the transcontinental railroad's western section.
Quarry Lakes Regional Recreation Area is the culmination of many years of planning and partnership between the Water District and the East Bay Regional Park District. The property that now comprises the park was acquired by the two agencies between 1975 and 1992 through purchase, donation and inter-agency agreements. Of the park's 471 acres, some 350 acres are the lakes.
The first phase of park construction began in 1997, when the Alameda County Water District used grading equipment to flatten the slopes of the quarry pit. This minimized erosion and sedimentation, while also creating land contours more suitable for parkland.
Then in August of 2000 the Park District began creating the recreational facilities at Quarry Lakes. These include turfgrass lawns, picnic areas, shade pavilions, a swim beach, a boat launch ramp, and a trail network.
Cost of the project's first phase was $5.8 million, of which $3.65 million was a grant from the City of Fremont Redevelopment Agency. The remainder came from Measure AA, the Park District's open space bond measure approved by voters in 1988.

Our VineyardQuarry Ridge's estate vineyard is planted on ideal Fingerlakes soil consisting of shale, sandy loam, and limestone ridges througout. Nestled down close to Cayuga Lake gives a unique microclimate to help ripen the fruit throughout the growing season and help the vines winter over year after year.
Currently at 10 acres planted, the Estate Vineyard consists of several different clones of 4 different varietals. We have one acre each of Clone 828, 667, and 115 Pinot Noir, one acre each of Clone 1 and 332 Cabernet Franc, one acre each of Clone 95 and Colmar Chardonnay, and finally one acre each of Clone 110 and 198 Riesling.
Clearly marked rows throughout the vineyard allow for our winemaking team to keep our clonal varietals seperate through the winemaking process, or even blend them together in order to make the best possible estate wines.
The Quarry Exhibit Hall allows visitors to view the wall of approximately 1,500 dinosaur bones in a refurbished, comfortable space. Here, you can gaze upon the remains of numerous different species of dinosaurs from the Late Jurassic period, including Allosaurus, Apatosaurus, Camarasaurus, Diplodocus, and Stegosaurus, along with several others. There are even several places where you can touch real 150 million year old dinosaur fossils! Rangers are available to answer questions, help kids complete their Junior Ranger booklets, and occasionally provide talks on different topics related to the quarry or dinosaurs during the summer.
A quarry is a place where rocks, sand, or minerals are extracted from the surface of Earth. A quarry is a type of mine called an open-pit mine, because it is open to Earth's surface. Another type of mine, a subsurface mine, consists of underground tunnels or shafts.
The most common purpose of quarries is to extract stone for building materials. Quarries have been used for thousands of years. The people of Kemet, ancient Egypt, built the Great Pyramids with massive limestone and granite blocks cut by hand from nearby quarries. Each of these blocks weighs many tons. In ancient Rome, enslaved people and incarcerated people were often forced to do the extremely difficult work of cutting stones in marble, granite, and limestone quarries.
Methods of extracting stone and other materials from quarries have changed since the first quarries were mined in the Aswan area of Egypt. The earliest quarries were mined with hammers, picks, and chisels made of stone or metals such as bronze and iron.
Even communities that did not have stone buildings created quarries. The Lakota culture of the Midwest region of the U.S. and Canada did not quarry stone to build monuments or houses. At a site in Pipestone National Monument, in the U.S. state of Minnesota, they quarried for stones to make calumets, or ceremonial smoking pipes. Calumets, made of a type of metamorphic rock called catlinite or pipestone, were important for creating lasting treaties, or agreements between groups of people.
Quarrying material for use in building materials was much more work. Stones had to be carried or dragged out of quarries manually. Stones could also be hauled with pulley systems involving ropes and moveable wooden tracks or sleds. This process often involved thousands of slaves and other workers.
On Easter Island, for example, almost the entire community had to be involved in the quarrying, carving, and transportation of statues. The rock for these statues, called moai, was hauled all over the island from one quarry. The heaviest moai weighs 86 tons. Scientists are still studying how these ancient Polynesian people transported their quarried rock.
Today, people use mechanical tools to mine quarries, including drilling equipment, blasting equipment, and hauling equipment. Industrial drills with diamond tips are used to cut into hard rock. Some miners use explosives to blast away unwanted material to access the desired rock. Finally, materials are hauled away by enormous mining trucks. Some mining trucks can carry more than 350 tons of material.
Dimension Stones and Aggregate
Different types of stones are mined for different purposes. The two most common types of quarry material are dimension stones and aggregate.
