It is very interesting to me that no pre-Clovis sites have been found in North America, but we have Monte Verde in Chile. Are the pre-Clovis North American sites there and just haven't been found and identified as pre-Clovis?

PreClovis sites have been found in North America, but until the journal referees are chosen for ability rather than seniority (or lack of other employment)...
See that link (or a Google search) for info on the Calico site, or Cactus Hill, or click the "GGG" keyword above. :')
