Cimarron National Grassland — Rockhounding in Morton County, Kansas
Updated July 2026
Cimarron National Grassland covers about 108,000 acres in the far southwest corner of Kansas and is the largest tract of public land in the state, managed by the U.S. Forest Service. Its Ogallala caprock and Cimarron River gravels shed agate, jasper, chalcedony, chert, and petrified wood, and this is one of the few places in Kansas where casual rockhounding is expressly allowed on public ground. Point of Rocks, a fossiliferous bluff above the Cimarron River, anchors the collecting corridor. Reported finds include agate, jasper, chalcedony, chert, petrified wood.
