The town is home to many glacial features including drumlins, eskers, and glacial erratics. Ground moraines may be modified into drumlins by the overriding ice. The park contains several glacial landforms such as drumlins and moraine. The Wisconsin glaciation formed drumlins in Milford&colon; Clark, Burwell, Eels, Bryan and Merwin hills. The majority of drumlins observed in North America were formed during the Wisconsin glaciation. The landscape is mostly flat though there is also some evidence of moraine and drumlins. The terrain contains many drumlins from past glaciation. These drumlins cannot be explained by the addition of soft sediment to a core. It contains Ireland's best example of sunken drumlins. Discovery of the Namibian drumlins was reported in 2019. Fields House, located in Newport, filled in for Wester Drumlins. However, it does not provide a unifying explanation of all drumlins. The scenes at Wester Drumlins were shot in a derelict house in Newport. Drumlins and ribbed moraines are also landforms left behind by retreating glaciers. Drumlins and drumlin clusters are glacial landforms composed primarily of glacial till.
