|Down on Oldshoremore Beach I encountered a group of visitors who were puzzling over some holes in the rocky cliffs.|
Giant mice, maybe, with tungsten carbide teeth?
The holes are the result of geological core sampling. A hollow drill has been bored into the rock and then the resulting column of rock snapped off and retrieved, no doubt now gathering dust in some display cabinet or sample drawer somewhere.
The geology in this tiny corner of Scotland is dominated by Lewisian Gneiss, a type of rock that formed almost 3 billion years ago and ranks amongst the oldest rocks in europe. This makes the area very interesting to geologists. Also prominent in the area are Torridonian sandstones and a variety of quartzite rocks.
