1841 | Louisiana’s Border with the Texas Republic | International Border Marker | Louisiana History

In April 1841, survey crews planted a larger granite block in the ground near the 32nd parallel to mark the United States’ international border with the Republic of Texas. The marker is still on the meridian today near Logansport. This Louisiana History Minute tells the story of the only international border marker standing within the contiguous United States.
