Glacial erratics, often simply called erratics, or erratic boulders, are rocks that have been transported by ice and deposited elsewhere. The type of rock (lithology) that the glacial erratic is made from is different to the lithology of the bedrock where the erratic is deposited.

It consists of both mineral grains and rock fragments. It tends to be poorly sorted. A glacier is indiscriminate in terms of the particle sizes it carries, so deposits directly from the glacier are likely to be very poorly sorted. Glacial deposits are among the least well sorted of all sediments.

Roches moutonnées are big chunks of rock on the landscape, with one side that is quite smooth, eroded by abrasion. The other side is much more rough, eroded by plucking.
