It was gradually reduced in size and in the 21st century is known as the present-day Siletz Reservation.
The Coast Reservation was established on November 9, 1855, by executive order for the coastal Indian tribes of Oregon.
[1] It was intended for removal of tribes involved in the Rogue River Wars from southern Oregon, as well as for small struggling tribes whose land the federal government wanted to take over for European-American settlement.
The original reservation's western boundary ran 105 miles along the Pacific Ocean from present-day Dunes City in the south to Cape Lookout in the north.
[2] The eastern boundary was roughly the summit of the Central Oregon Coast Range.
