The tristate monument of "LouTexArk"

Between Atlanta, TX and Rodessa, LA, this monument is just on the east side of the highway embedded in the root of a giant tree. The three states of Louisiana, Texas, and Arkansas meet at this monument. The north/south line at this spot was determined by the Onís-Adams Treaty of 1819. A line would be drawn due north to the Red River from the spot where the Sabine River crossed the 32nd parallel North latitude. This was to create a land buffer between the predominantly French settled areas of the southward flowing section of the Red River from the border of Spanish Texas. 32N is a significant line to Texas which determined the shape of Texas in the west and in the east. The north/south line was an international border between Spain and the United States; then Mexico and the United States; then the Republic of Texas and the US, before it finally became the state boundary between Texas/Louisiana, and Texas/Arkansas.
