Wales is a country that is part of the United Kingdom. It is bordered by England to the east, the Irish Sea to the north and west, and the Bristol Channel to the south. It had a population in 2011 of 3,063,456 and has a total area of 20,779 km2 (8,023 sq mi). Wales has over 1,680 miles (2,700 km) of coastline and is largely mountainous with its higher peaks in the north and central areas, including Snowdon, its highest summit. The country lies within the north temperate zone and has a changeable, maritime climate.
The quarries are located near the village of Pontsticill, overlooking Pontsticill Reservoir. Abercriban Quarries comprise two small disused quarries. The site is of special interest for the rock exposures of the Grey Grit Formation of the Upper Old Red Sandstone, these exposed rocks span the boundary between the Carboniferous and Devonian periods of geological time, approximately 360 million years ago.[1]

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
