Yeah, the Burrows Cave "artifacts" are laughably bad hoaxes. This is a natural consequence though of more than a century of the suppression and degradation of the copious evidence for precolumbian navigation in, to, and from the Americas by various maritime peoples, not even beginning with the Maritime Archaic.
Homing In On The Red Paint People
by Angela M.H. Schuster
Buried between 4400 and 3300 B.P., the dead--along with offerings of tools, animal bones, carved animal effigies, and small, white quartz pebbles--were covered in red ochre, earning them the moniker the "Red Paint People."The Mystery of the Lost Red Paint People
Maritime Archaic Tradition
The origins of the Southern Branch Maritime Archaic people are obscure. Shortly before 6,000 years ago a new stone tool complex appears in southern Labrador. The people who made these tools preferred locally-available cherts and rhyolites to the quartz, quartzite and Ramah chert of the Northern branch people. By about 5,000 or 4,500 years ago these people had become established on the coast of southern Labrador and parts of the central coast... The Southern branch people were the first humans to colonize the Island of Newfoundland.
