Watercolour image by John Clerk of Eldin (1728-1812), completed in 1785 or shortly thereafter, and rediscovered as one of the “lost drawings” intended for inclusion in the never-completed third volume of James Hutton’s Theory of the Earth. The image is a stylized but accurate geological map of the key exposures in the River Tilt that influenced Hutton’s thinking on the origins of granite. The flow direction of the river is towards the top of the image, in a southwesterly direction. The rectangular areas at the top of the image are the foundations of the bridge that used to exist here.
