The image shows a fairly large rock on the edge of a trail in the Adirondack Mountains upstate New York. It’s a glacial erratic. Glacial erratics are the stones and rocks that a glacier picked up as it advanced and then left behind as it melted. Glacial erratics can be carried for hundreds of miles and may differ significantly from the rocks native to the area in which it rests. The term "erratic" comes from the Latin "errare," which means "to go astray." Glacial erratics can be seen along many trails throughout the Adirondacks
For the #RockinTuesday theme: a glacial erratic on the Heron Marsh Trail at the Paul Smiths VIC. The retreating glacier left a lot of these behind. wildadirondacks.org/adirondack-g...
