| Location | The River Balder upstream of Balderhead Reservoir |
| Civil Parish | Cotherstone |
| Brit. National Grid | NY 899 181 |
| Altitude | 335m |
| Geology | Small ravine cut by upper reaches of Balder Beck through Namurian shales and glacial till. |
| Record Name | Shap and other erratic boulders on the upper reaches of the River Balder |
| Record Description | A recent walk on the banks of the River Balder upstream of Balderhead Reservoir identified at least four Shap granite erratic boulders together with a number of other erratics of different rock types. It is of significance that Shap erratics were present upstream only as far as NY8935 1758. |
| Additional Notes | This walk is one of a series of walks in search of Shap erratic boulders on the upper reaches of the tributary streams of the R.Tees which rise on North Stainmore. These walks have the aim of identifying the line taken by the ice stream which carried Shap, other volcanic erratic and sedimentary rocks from the North and West- from Vale of Eden, the Lake District and from Galloway, across the National Divide north of the Stainmore Gap, to the South and East. |
