Markland
Markland is the name given to one of three lands on North America's Atlantic shore discovered by Leif Eriksson around 1000 CE. It was located south of Helluland and north of Vinland.
Although it was never recorded to be settled by Norsemen, there were probably a number of later expeditions from Greenland to gather timber. A 1347 Icelandic document records that a ship has come off course and ended up in Iceland in the process of returning from Markland, without further specifying where Markland is.
Location
Markland has been suggested to have been part of the Labrador coast in Canada, as Labrador lies in the heavily forested taiga region of the Northern Hemisphere north of the location of Vinland on the island of Newfoundland. However, the climate and hence the vegetation in this particular region may have changed significantly since the sagas were conceived - see Medieval Warm Period and Little Ice Age.
The particular part of the Labrador coast is difficult to pinpoint, as Helluland has been placed everywhere from Baffin Island to the northern Labrador coast beyond Groswater Bay to the southern Labrador Coast.
