Crunkly Ghyll is a half-mile long gorge carved by glacial melt waters, through which passes the River Esk, near Lealholm, in Yorkshire.[1]

The author of Aquatic Wonders of Yorkshire: A Wizard's Field Guide collected a Grindylow specimen from Crunkly Ghyll, showing the distinct physical traits of the local population: the work included a sketch of said Grindylow as an illustration of the surprising degree of physical variation among Yorkshire Grindylows.[2]
