Louisiana Purchase State Park near Brinkley
In 1803 President Thomas Jefferson signed the papers to purchase the
vast territory of Louisiana from Napoleon's France, doubling the size of
the United States. The first chapter of the history of the Louisiana Purchase was written in 1815, when President James Madison ordered an official
survey of the area to establish a system for distributing to veterans
of the War of 1812 land they had been promised.
On October 27, 1815, a survey party led by Prospect K. Robbins headed
north from the confluence of the Arkansas and Mississippi rivers on an expedition to
establish a north-south line to be known as the Fifth Principal
Meridian. The same day, a party led by Joseph C. Brown departed westward
from the junction of the St. Francis River and the Mississippi to
establish an east-west line, known as a baseline.
The crossing of the two lines would be the initial point from which
future surveys would originate. Robbins' party had traveled north almost
56 miles when they crossed the baseline surveyed by Brown's party. Two
gum trees about 18 inches in diameter were marked as witness trees to
delineate the initial point, some 26 miles west of the Mississippi.
Both the meridian and the baseline would later be extended, and land
surveys for all or parts of the Louisiana Purchase states west of the
Mississippi would subsequently be measured from this point in an eastern
Arkansas headwater swamp.
The site went unheralded for more than a century. In 1921, two
surveyors discovered the witness trees, and the L'Anguille Chapter of
the National Society of the Daughters of the American Revolution in
nearby Marianna placed a monument there in 1926.
Louisiana Purchase State Park
Two hundred years after the purchase, the Louisiana Purchase Historic
State Park near Brinkley preserves this site and the history of the Louisiana Purchase.
Designated a National Historic Landmark in 1993, visitors can walk an
elevated, barrier-free boardwalk through the swamp to this monument to the history of the Louisiana Purchase,
experiencing the sights and sounds
of the wilderness much as the original surveyors did.
