Striations

These occur on rock surfaces that have been abraded by glaciers where their frequently smooth or polished appearance also exhibits parallel scratches or grooves known as “striations”. Rock fragments embedded in the basal layer of the ice, which scraped the underlying bedrock as the glacier flowed passed, produced these striations.
