Mendocino Indian Reservation

Its area was 25,000 acres (100 km2) and its boundary extended north from what is now Simpson Lane at 39°24′43″N 123°48′30″W / 39.41194°N 123.80833°W / 39.41194; -123.80833 to Abalobadiah Creek and east from the Pacific Ocean to a north–south line passing through the summit of Bald Hill.

In the summer of 1857, First Lieutenant Horatio G. Gibson, then serving at the Presidio of San Francisco, was ordered to take Company M, 3rd Regiment of Artillery to establish a military post one and one-half miles north of the Noyo River on the Mendocino Indian Reservation.

[2] In June 1862, federal troops had been withdrawn to the East to fight in the American Civil War, being replaced by Company D, 2nd California Infantry, that was ordered to garrison the post and remained until 1864.

In October the Fort Bragg garrison was loaded aboard the steamer "Panama" and completed the evacuation and abandonment of Mendocino County's first military post.

The Mendocino Indian Reservation was discontinued in March 1866 and the land opened for settlement three years later.
