| Caption: | Esker at Hunstanton Park, Old Hunstanton, Norfolk. |
| Description: | Looking south at Hunstanton Park, Old Hunstanton. Hunstanton Park Esker showing the detail of glacial sand and gravel. This small section, the only one in the gravel ridge, shows a crude bedding dipping along the axis of the ridge away from the observer. The larger pebbles are composed of locally derived materials, flint, chalk and Hunstanton Red Rock. Carstone, which breaks down easily on weathering, is represented only in the sandy matrix. Many of the smaller pebbles can be recognized as having been derived from Northern England. These include coal, Carboniferous sandstones, Triassic quartzites, igneous and metamorphic rocks. An esker is a long winding ridge of glacial sands and gravels. They formed beneath or within an ice body either from infilling of streams within the glacier or deposition at the mouth of a sub-glacial stream as the ice retreated. |
