Syenite at Scale Force (Red Pike)??

 

On page 8 of the Red Pike (Buttermere) chapter, Wainwright says that the subsoil next to Scale Force is coloured red due to syenite. I can find no up-to-date reference to syenite in England other than ones that seem to take it from Wainwright. It turns out that syenite is like granite but has much less quartz. see this There are other difference. The granite in Ennerdale is a redder granite. However, BGS seem to list several sites in Scotland, the nearest of which in the Nith Valley might be visible from my kitchen window! I did find Adam Sedgwick's The Geology of the Lake District on Google Books. This was published in 1853. On page 44 he calls the Ennerdale rock "syenite" as distinct from Eskdale Granite. This might well be Wainwright's source. I need to do more research on this.
