Shaken Not Stirred

Summer. 30,000 Islands. From flower pot size to big enough for a country. These are some of the planet's oldest exposed rock, at about 3 billion years old, gneiss and granite, the sparkle of mica schist, the dark smokey gneiss veined with yellow and white quartzite or pink feldspar granite, mostly layered like cakes and then called banded gneiss. It wasn't until geologists had a good look, that we found out that this archipelago of brooding islands had been stacked a lot higher, into mountains and whole chains of them. The last ice age and a few more besides bulldozed them.
