I have just added this to the map of places to fly your drone at Drone Scene:
Grinton Smelt Mill (also known as How Mill) is a ruined lead mining and processing site on Cogden Moor, south of Grinton in Swaledale, North Yorkshire, England. The site was built in its present form c. 1820 for the specific purpose of processing lead won by hushing and hydraulic mining. The buildings and stone flue are now grade II* listed structures and all are scheduled monuments. The site is recognised as being the best preserved lead mining site in the Yorkshire Dales.
The site is located in an SSI and does cover a few species of birds, being winter, most of these have migrated to warmer climates.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 30/12/2025. It remains the responsibility of any pilot to check for any changes before flying at the same location. Landowner permission may be required before taking off.
