| Caption: | Galleries in Westphalian A (Lower Coal Measures) sandstone, Hown's Quarry, Consett, Durham. |
| Description: | Looking north-west at Hown's Quarry. The upper part of the sandstone was quarried in galleries when the overburden became too great. Much of the housing in Consett was built out of this stone. The quarries have been disused since the turn of the century. The sandstone is below the horizon of the Victoria Coal. Sandstone for use as a building stone, as a roofing stone, and also to a lesser extent as an aggregate, was formerly quarried widely throughout the district. Working was always on a relatively small scale, and reserves in general have hardly been touched. The many beds that have been worked for good stone in Durham include some of the sandstones in the higher part of the Stainmore Group and the lower part of the Lower Coal Measures, and higher in the sequence the Durham Low Main, High Main, Seventy Fathom and Grindstone posts of the Middle Coal Measures. Hown's Gill is regarded as one of the larger sandstone quarries in Durham. |
