Fresh Glacial Striatations

Glacial striations are always a pleasure to see. They are a reminder of the past. I came across an excellent fresh exposure where even the finest scratches in the bedrock were readily apparent. The site was along a shoreline. Periodic high waves have been removing the glacial drift that is covering the glacial striated bedrock exposing very unweathered striatations etched into the metamorphosed basalt.

The site is on the south shore of Decatur Island
