The SDM site is a typical Paleo Indian site.
Typical in the fact that Paleo sites are all quite
different from one another when you compare
artifact inventories by category, not counting the
majority of which are non-descriptive items of
Paleo stone artifacts show an amazing range of
shapes and sizes, probably due to the size and
quality of the raw material.
The SDM site material seems to be entirely of
local glacial origin.
