The 809R lookout station design on an enclosed 30 foot steel tower is believed to be exclusive to CDF. The subject facility has undergone few changes since its construction. Working plans were not located for this specific building but the structure conforms to the standard 809R working plan with the following exceptions: steel fire escape ladder with steel trap door through the catwalk (located on the west side of the tower) , metal exterior doors, aluminum sliding windows, and composition roofing all added. The traditional, shed roof addition (garage door) tower entry is absent. Because of the tower's late construction date (relative to this design type) some of these deviations from the standard working plan may have been incorporated at the time of erection. There are only nine 30' 809R towers still left in existence.

Two Rock's summit features two rocky outcroppings spaced about an 1/8 of a mile apart. The lookout is on the southeast point. The station is surrounded by brush, oak and Douglas fir vegetation types interspersed with large meadow areas. The site is not accessible to the public, being 3.2 miles from the nearest paved road; 3.1 miles behind a locked gate. The tower is closed due to funding constraints. (MVT 10/91)

Two Rock was permanently closed in 1994. The land and structure were returned to the private property owner from whom the land was leased.
