Barneston Limestone (Lower Permian) of eastern Kansas
The Barneston Limestone is well exposed on the north side of the road cut at milepost 305 on 1-70 in NW¼SW¼Sec.30, T.1lS., R.6E., Geary County, Kansas (Fig. 1), about 10 mi (16 km) east of Junction City. Vehicles traveling east should continue to exit 307 (McDowell Creek Road), pass under 1-70, and return westward to milepost 305. Because Kansas law prohibits pedestrians from crossing a divided highway, vehicles should be parked on the north side, off the pavement and passengers should exit on the right-hand side. Keep far away from the traffic lanes while examining the rocks. The upper two-thirds of this section can be examined closely by walking up the hill on the west side of the road cut.
