Sop's Arm is a local service district and designated place in the Canadian province of Newfoundland and Labrador. The community was formed in the 1930s and 1940s by families moving from surrounding communities, including Jackson's Arm. In the 1950s and 1960s families from nearby Sop's Island moved to Sop's Arm, towing their houses across the channel of water.
Today, the community of Sop's Arm stretches from the mouth of Main River, a river provincially well known for its salmon fishing and white-water kayaking, north to Schooner's Cove.
Traditionally, the economy was based on the cod and salmon fishery, forestry, including sawing lumber and cutting wood for the Corner Brook Pulp and Paper Mill.
Possible Norse hunting pits have been excavated near Sop's Arm. Watson Budden, a local resident, showed these in 1961 to Helge Ingstad, the archaeologist who investigated L'Anse aux Meadows, the only Viking settlement to be attested in North America, which is approximately 200 kilometres (120 mi) away. His nephew Kent Budden assembled a collection of suspected Norse artefacts in the area and displayed them in a Viking museum. Kevin McAleese, a curator of archaeology and ethnology at the Provincial Museum of Newfoundland and Labrador, led an investigation of the pits in 2010 and has said that no other cultures in the area are known to have use deadfalls to hunt, but doubts Budden's artefacts are Norse.[1][2] It has been argued that Sop's Arm is the Straumfjörð of the Vinland sagas.
