Record Name | Two glacial erratic boulders of Carbiniferous Limestone at the Northern Edge of Semer Water Lake. |
Record Description | Semer Water is the remnant of a much more extensive post glacial lake formed until the River Bain breached the lateral moraine at the edge of the Howgill Ice and cut the pictureque river gorge above Bainbridge. (Kendall and Wroot, 1924 'Geology of Yorkshire',536/7). During the full glacial this glacial lake, then 3 miles wide and ice dammed by the Howgill Glacier extended for a distance of four miles further up Raydale,Cragdale and Bardale cutting the ice margin channelacross the NW shoulder of Addlebrough known as Hukermire Moss and also the ice margin channel at Harker Mire which seperates Addlebrough from The Stake Fell, both channels at an elevation of 375m. |

Additional Notes | The peat infil to both Hukermire and Harkermire have been sampled for pollen by Ann Honeyman and her pollen reports at these sites have provided the basis for the understanding of the vegetational history of this area, see also SWAAG Record 661.
The prehistory of Semer Water Lake Edge and of the surrounding fells is introduced in more detail in SWAAG Record 661. |
