| Caption: | Glacial overflow channel, Hown's Gill, near Consett, Durham. |
| Description: | A deep glacial overflow at Hown's Gill, Consett, looking south-east from Whinney Hill, Moorside.The deep channel largely cut into sandstone of Westphalian A (Lower Coal Measures) Carboniferous age and above horizon of Marshall Green Coal. This dry valley severs the watershed between the rivers Derwent and Browney and in late-glacial times carried the ice-dammed drainage of the Derwent into the Browney. The Hown's Gill Viaduct up to 37 m. (120 ft.) above the valley floor connected the former railway between Consett and Stanhope (via Rowley). A dry valley is a valley in which there is no existing river. A glacial overflow channel or meltwater channel is a channel cut by the action of glacial meltwaters or by water from an ice-dammed lake. They are usually steep-sided, flat-floored and unrelated to the present drainage system. |
