Those that argue against Europeans entering North America in pre-historic (or even later ) times often claim that such ocean voyages were beyond the abilities of the ancients. It was also said that the Indians walked into North America from Beringia. When geologists showed that ice sheets covered the land during the period when Man first entered the Americas from Beringia, an "ice-free corridor" was suggested as a route. Again, geologists showed that such a corridor did exist, but during the wrong period. It is now thought that the Indians skirted the iced-over Pacific coast in boats... Kinda like how ancient Europeans were allegedly unable to have done along the Atlantic ice pack.
And yes, isn't it curious that while Solutrean points resemble Clovis technology, no similar stone tool tradition exists in eastern Siberia? Equally curious is the appearent migration of Clovis technology from the east coast westward, rather than from the northwest spreading southward.
Except for the base of the point, very close I would guess, from the photo that I found. I found a web site that proposed the something similar with a nice picture of the Ice conditions in Solutrean times.
If that picture is accurate, it would be logical to find the oldest Clovis finds in the South East.
