An Archaeological Reconnaissance of the Over-the-Horizon Radar Project Transmitter Site, Buffalo Flat, Christmas Lake Valley, Lake County, Oregon

: The reconnaissance identified 36 prehistoric cultural resources sites. Evidence from these sites provides for a distinction between lithic scatters, plant processing sites and fire-cracked rock/groundstone assemblages. Stylistic analysis of collected projectile points suggests the area was used, perhaps intermittently, throughout the Holocene but more intensively during the last 2000 years. Because the sites have potential for contributing to our understanding of the subsistence/settlement systems operant during the mid-to- late Holocene in the Fort Rock Basin, further investigation at the sites is deemed appropriate.
