There is a new breakwater being built beside the pier on Iona, to help make the service less liable to disruption by wind/swell. Here it is yesterday, at about half of the final length! Sadly, it's not using local rock: this currently contains 33k tons of rock: mostly Norwegian grey-brown granitoid (I'm trying to find the source) plus some pink-pale grey Glensanda Scottish granite. Not bad, but it would be better if it was local Ross of Mull granite IMHO. #Geodiversity #LocalStone. #Iona

This morning's #DogWalkingGeology The Camas Tuath (North Bay) quarry, in the Ross of Mull Granite, opened by Alan Stevenson, for the Northern Lighthouse Board, to provide granite for Skerryvore Lighthouse in 1839. It was worked until around 1857, and also provided stone for Ardnamurchan lighthouse, as well as ornamental stone. Sad that none of this beautiful stone is worked today ☹️ #Geology #LocalStone #Lighthouse #Mull
