Novaculite was imported, e.g pg 125 in Ford & Webb: “Access to magnetite, hematite, galena, gray-white chert, novaculite, possibly slate and shale, and other minerals from the Ozarks of southern Missouri and northern Arkansas would have been by way of the Arkansas and White rivers (or Mississippi and White).” Pg 51: An easily recognizable material, novaculite, was imported for the manufacture of projectile points by the Poverty Point people. This stone, composed of cemented quartz crystals, is available in northern Arkansas.”
