Map showing the Lincolnshire Wolds and the southern part of the Yorkshire Wolds, separated by the Humber west of Kingston upon Hull
The Humber Gap is a term for the geographic gap between the roughly north–south running line of hills formed by the
Yorkshire Wolds and the
Lincolnshire Wolds, formed by the west–east running
Humber Estuary.[1]
In the geological past the gap has formed part of an ice barrier due to glaciers during the
ice age resulting in damming and formation of a 'Humber Lake',[2][3] and also forms a geological division.[4]
In modern times the gap has formed a natural choice for transport routes, such as the railways.[5] The
Humber Bridge also crosses the Humber close to the gap.[1]
