Gibson Knott
Encyclopedia
Gibson Knott is a fell
in the English Lake District
, an intermediate height on the ridge between Greenburn and Far Easedale in the Central Fells
.
. A complex system of daleheads to the east of this apex resolves itself into Calf Crag
, a broad-topped ridge featuring a number of rocky tops. This ridge then splits into two arms about the head of Greenburn, the southern branch running on to Gibson Knott and Helm Crag
.
Between Calf Crag and Helm Crag the ridge narrows to perhaps a hundred yards in width, gradually curving to the south east on its one and a half mile course. There are several tops on this section, Gibson Knott being halfway along.
The southern face above Far Easedale is rocky, Horn Crag being the principal feature. The northern side drops more gradually to the upper gathering grounds of Greenburn Bottom. There is little loss of height going westward from the summit before the climb to Calf Crag begins on a broadening ridge. Between Gibson Knott and Helm Crag lies the depression of Bracken Hause at around 1,100 ft.

Lapilli
Lapilli is a size classification term for tephra, which is material that falls out of the air during a volcanic eruption or during some meteorite impacts. Lapilli means "little stones" in Latin. They are in some senses similar to ooids or pisoids in calcareous sediments.By definition lapilli range...
