First set at the junction of the States of MN and IA, and the Dakota Territories in 1859. The marker was removed in the early 1900s after virtual destruction by vandals, it was repaired and re-set in 1938 by the contiguous counties at the direction of the Department of the Interior. In 1979, the marker was broken from the base by vehicle traffic, and repaired and re-set at this site in 1980, by Lyon County, IA, Rock County, MN, and Minnehaha County, SD. Also in 1980 there was a flush marker set at the original location. This Tri-State Marker was dedicated to the pioneers of Siouxland on the 26th day of October, 1980.
