| Lithological Description: |
Well bedded cross-stratified gravel and sand that typically forms upward coarsening sequences. Clasts are generally rounded to well rounded and comprise a mixture of Permo-Triassic and Carboniferous rocks, as well as igneous and metamorphic rocks derived from the Lake District. Deposit fines downwards into horizontally bedded sand with horizontal and climbing ripple lamination. |
| Definition of Lower Boundary: |
Generally conformable on the Fishgarth Wood Till Member of the Gosforth Glacigenic Formation in the Drigg Hall Carleton area; on the How Man Till Member between St Bees and Braystones and on the Rothersyke Till Member in the Ehenside area. |
| Definition of Upper Boundary: |
Unconformably overlain by Holocene deposits such as Blown Sand and by Late Glacial to Holocene peats near its type site. |
| Thickness: |
To 20m |
| Geographical Limits: |
Western Cumbria within (seaward of) the limit of the Gosforth Oscillation. Typically on the coastal lowlands between Gosforth, Seascale and Drigg. 1:50k Sheet 37 Gosforth. |
