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.
