Two Rock Union School has a history of change and growth.
Originally, three separate schools served the community. Iowa School,
the first public school in Sonoma County, was established in 1852;
Walker School in 1876; and Two Rock School in 1885. The three schools
were unified under one school board of trustees in 1919. In 1952, the
present site was chosen for the unification of these schools into one
location. Two Rock Union School was built on five acres deeded to the
district by the U.S. Government at a total cost of $61,588.00.
Additional rooms and property have been added periodically.
Two Rock Ranch
(U.S. Coast Guard Training Center)
The Two Rock Ranch Station was established by the War Department
in August 1942, after acquiring 876 acres of ranch at a price of
$94,344.00. During WWll, the U.S. Army used the site as a
communications station. The Army retained the original ranch
structure to camouflage its military status. False furrows were
graded around the operations area to make the ranch look like any
other ranch from the air. More structures were added by the Army
during the 1950's and 1960's. On July 1,1971, the Army transferred
the "ranch' to the U.S. Coast Guard to be used as a training center.
Two Rock Valley
The Two Rock Valley was given its name because of the two
prominent grey stones standing a few feet apart on a gentle slope
above the Petaluma-Bloomfield highway. Two Rock was originally called
"Dos Piedras". A band of tribal hunters first carved a trail between
the rocks. The trail was later used by the Russians and Spanish. The
rocks became landmarks on the trail from Mission San Rafeal to Bodega
and Fort Ross. Being a natural landmark, they became "cornerstones"
for large Mexican land grants.
