Glacial Grooves are straight parallel grooves found on the exposed surface of bedrock. These grooves were formed by the coarse gravel and boulders being dragged along underneath the retreating glacier. This resulted in a scrapping or gouging of the surface of the bedrock, thus creating the glacial grooves. It is believed that these glacial grooves indicate the direction of flow of the retreating glacial ice. Glacial grooves are found in many parts of the world. They can vary in size, from a few inches deep to a few feet in depth.
