Featured above is a view from the top of Quaker Ridge in Casco, Maine. Striations can clearly be seen on this metamorphic rock outcrop. When glaciers retreated here, approximately 12,000 years ago, these linear marks were left behind. A shallow covering of snow had melted off of the rock's surface on this early winter's day, allowing the striations to be examined in some detail. My dog, Betty, a Newfoundland or "newfie" provides scale to the outcrop. Photo taken on December 15, 2121.
