Trip Report - June 21, 1991 - Jack Parsell
ACCESS ROUTE: From South West City, MO, go S about 1 mile on Route 43 which becomes OK Route 20. The monument is on the W side of the highway just off the shoulder. When the west boundary of Missouri was surveyed in 1823, a large stone post was set to mark the SW corner of the State at a point on latitude N 36° 30'. In 1906 this position was determined to be lat. N 36° 29.267', long W 94° 37.048'. The present monument was erected by the Ozark Culture Club in 1915 with part of the old marker post embedded in it. The whole assembly was installed on a new base in 1955. It is not known whether the present monument assembly was moved to its present location to allow for widening the highway.

The access info doesn't vary from the guide via secondary roads. From South West City go south on Rt 43 aprx. 1 mile. This formidable marker, across the road from the "Corner Stone Station," is hard to miss.
