There is a section of rock near the harbour in Lower Largo which has a honey-combed appearance. The hollows are home to many limpets and barnacles. In places the rock appears to have a crust over the top. (See photo below) Interesting to speculate how these features were formed. No doubt a geologist would be able to tell me. There was considerable volcanic activity in this area 300 to 350 million years ago. Largo Law is the remains of a volcanic neck. Wonder if the holes were formed by gases in molten material, and the crust on the top formed when the outer surface cooled.
