Threshfield Quarry, a disused limestone quarry which closed in the year 2000. The owners, Tarmac, undertook a programme of site clearance and restoration ground works to prepare the site for long term access and development.
The quarry was a major employer for almost a century, and a rare industrial presence in this high-quality rural landscape. It is now the largest brownfield development site in the Yorkshire Dales National Park, partly designated for employment use and partly for natural regeneration.

Linton Falls Hydro, a hydroelectric generating power station on the River Wharfe at Linton Falls. The power station is located on the same site as a hydroelectric scheme that was first opened in 1909, but had closed by 1948. The new scheme, which opened in March 2012, uses the original building which is now a scheduled monument. The plant uses two screw turbines to generate the electricity.
