Sunny view large angular rocks impeding water flow in upland stream channel of Trough Brook, Marshaw Wyre, Trough of Bowland, UK
The Marshaw Wyre, a headwater stream of the River Wyre that enters the sea at Fleetwood, is incised into glacial deposits supporting shallow-rooted beech trees and conifers downstream of the exposed moortops where the stream starts. The stream, in dry weather, is reduced tom a trickle. It responds rapidly to heavy rain, however. The steep slopes, thin soils and impermeable bedrock of the upland valley give rise to the rapid overland flow of rainwater. Large boulders entering the stream from the steep hillsides impede the flow of water, despite the steep gradients on the upland slopes. Trough Brook, flowing from a rain soak at the summit of the Trough of Bowland (a short distance to the right of shot), jojns a neighbouring stream at Trough Bridge (some distance to the left of shot) to form the Marshaw Wyre. The narrow Lancaster-Dunsop Bridge road follows the brook. The location is popular with both tourists and geography students.
