| The river crosses the Dent Fault just downstream of the marker post, and is 'visible'
as a gully in the river bank. The softer rocks downstream have been eroded into a
more gentle valley. |
||
| Downstream the rocks are Brathay Flags, from the Silurian period, 440-410 Myrs old;
upstream the limestones of the, older, Carboniferous period, 345-280 Myrs old. The
fault occured during mountain building about 290 Myrs ago, the limestones are crumpled
up against the brathay flags. The fault was first discovered and interpretted by Adam
Sedgwick. |
