Dry Rigg Quarry

Dry Rigg Quarry is a quarry at Helwith Bridge in North Yorkshire, England, located within the Yorkshire Dales National Park. The quarry produces a hard-wearing gritstone (also known as greywacke) which is listed as being nationally important for road building, and is one of four in the Yorkshire Dales National Park that produces this type of aggregate. The quarry operations have come under public scrutiny due to the amount of road traffic, leading to some of the output from Dry Rigg being moved from the adjacent railhead at Arcow Quarry. The quarry is situated in Upper Ribblesdale some 1.9 miles (3 km) south of Horton-in-Ribblesdale, and 5 miles (8 km) north of Settle.
