Coldberry Gutter

Coldberry Gutter (sometimes listed as Red Grooves Hush) is a narrow, incised west to east orientated gorge, on the watershed between and Newbiggin Beck and Hudeshope, near Middleton-in-Teesdale, County Durham, England. The site is believed to have been scoured out by hushing for lead and other minerals as it has two former lead mines at either end, however, modern-day evidence points to the gutter being a glacial meltwater channel, which was utilised by the miners. The Coldberry Gutter is thought to be the largest and most dramatic hush in the North Pennines.
