A survey was done on 640 acres in eastern Montana for additional oil and gas upgrading and development. Findings include thirty-two cultural sites, prehistoric tipi ring campsites, prehistoric lithic scatters, prehistoric campsites with hearths and lithics, campsites with lithic artifacts and old hole-in-top cans, historic herder camps, and the possible remains of the Keogh Road.
