Novaculite and chert weather out along the ridges and road cuts near Atoka. The rock ties the area to the same Ouachita geology that produces quartz crystals farther east. Reported finds include novaculite, chert. Below: coordinates, access notes, nearby spots, and trip-planning links.

Land & collecting status
Permission required before collecting
Requires landowner or agency permission before any collecting. Do not enter without explicit authorization.
Access note: Novaculite exposures are mostly on private land and along highway road cuts, so get permission before entering private property and do not collect on the roadway itself or dig into cut slopes. The material is hard and best gathered as loose float. Avoid active quarry ground.
Public-land rules vary by agency, season, and field office. The RockHoundR app pulls live BLM, USFS, NPS, and tribal overlays so you can see exactly which agency manages the ground at this spot.
