Caption: | Oblique aerial view of Sgurr of Eigg, looking north. |
Description: | The pitchstone forms a prominent steep-sided ridge from Bidean Boidheach south-east to the Sgurr seen in the photograph. It is thought to fill an ancient westward-draining river valley eroded into the underlying basalt lavas. The pitchstone has a black, vitreous to dark matt-grey appearance on fresh surfaces but weathers to a pale grey rock. Flow banding is common and columnar jointing is ubiquitous reaching one metre is diameter in the lower parts of the pitchstone mass. Sgurr of Eigg is a body of pitchstone which overlies Tertiary basaltic lavas, the latter can be seen in the foreground. Two other Tertiary igneous centres can be seen in the background; Rum and Skye. |
