Some of the boundary surveys in the southeast quadrant of Jackson State Forest by Knute Nelson (1960s) were tied to Two Rock so we are tying it into our control network. It is a spectacular spot with a view of several miles of the Mendocino coastline. It was a leased lookout but it is no longer leased by Cal Fire. The property owner is allowing us access to the site.

There are two stone pillars 12' apart (northeast and southeast corners of the old lookout house which is gone and two high rocks 12' west of them for the northwest and southwest corner. Roughly 10' south of the southwest rock is the azimuth mark:
