Chasing Centuries is a one-of-a-kind travel-history book that takes the reader along on an exciting and little known adventure at the crossroads of archaeology and botany that examines the depth and duration of human/Agave coevolution across the desert southwest. Travel with author Ron Parker as he discovers interesting assortments of unusual agaves apparently associated with archaeological sites long since abandoned by residents of extinct ancient cultures. These agaves appear to be anthropogenic cultivars; living archaeological relics developed and planted by indigenous pre-Columbian Native Americans, and many are still growing exactly where they were planted hundreds of years ago.
