Thunacar Knott

Thunacar Knott is a rocky mountain summit in the central Lake District region, rising to approximately 720 meters above sea level. The peak features two distinct high points, with the northern cairn holding special significance among fell walkers.

The summit was documented by Alfred Wainwright in his fell guide series, who established the northern cairn as the primary peak despite the southern point being marginally higher. This classification became the standard reference for fell walkers and remains influential today.

The summit forms part of the Wainwrights, Nuttalls, and Fellranger classifications, making it a target for mountain collectors seeking completion of these lists.

The main approach starts from the New Dungeon Ghyll area in Great Langdale, following established paths that pass through Stickle Ghyll valley toward the summit. Sturdy walking boots and weather protection are essential, as the exposed upper slopes can turn challenging quickly.

The summit displays exposed layers of Seathwaite Fell Formation rock containing volcanic material and conglomerate deposits that reveal millions of years of geological history. These geological features give visitors a direct window into the ancient processes that shaped the landscape.
