- Comments
- DiRa-9, Stirling Creek Bridge: Late Period artifacts include corner-notched projectile points similar to Northern Columbia Plateau sequences as well as variants of "Shuswap Horizon" types from the Thompson-Fraser region. Early Period projectile points include "Cascade"-like leaf-shaped types with serrated blade margins. Of particular interest is the large sample of microblades (>2000) and microcores manufactured primarily of local cryptocrystalline silicates.
