Anson Dart (1797–1879) was the Superintendent for Indian Affairs in the Oregon Territory from 1850 to 1852.
[1][2] Dart negotiated treaties with the tribes in the territory (now the states of Oregon and Washington), thirteen of which were negotiated August 5–9, 1851, at Tansy Point located in Warrenton, Oregon.
Dart's orders were to remove the western Oregon tribes to the east of the Cascade Range.
Dart finally settled on tribal reservations west of the Cascades.
Dart resigned in 1852 to be replaced by Joel Palmer who was very successful with his treaties negotiated in 1853-1855.
