Fluted spear points and knives are the characteristic traces
of the earliest people. Later Paleoindians did not use fluted tools,
and preferred to make their implements from glassy rocks that yield
a sharp, easily maintained edge. Many of the cutting tools, piercers,
and scrapers are unlike styles of later times, making it possible for
archeologists to identify the camps, dwelling places, and quarries of
the Paleoindians by their signature implements.
The earliest people were diligent and observant searchers,
locating the best sources of stone almost as soon as they arrived. Tools
have been found far from where they were made, suggesting that the Paleoindians
traveled extensively. It is unlikely their travel can be explained by
long-distance trade. With the population spread so thin, most groups
were probably unaware of each other.
