Lateral and terminal moraines of a valley glacier, Bylot Island, Canada. The glacier formed a massive sharp-crested lateral moraine at the maximum of its expansion during the Little Ice Age. The more rounded terminal moraine at the front consists of medial moraines that were created by the junction of tributary glaciers upstream. —Source: Natural Resources Canada Unattributed photograph.

Columbia Glacier in Alaska encroached on a forest as it surged in the early twentieth century, pushing trees, soil, rocks and debris as it advanced. This photograph was taken in 1914, several years after the glacier had begun to surge. Columbia Glacier is located in the Chugach Mountains of Alaska. —Source: D. K. Handy photograph/NSIDC
