This benchmark is located on South Twin Peak in
Twin Peaks Park. The disk is inlaid in a 4x12x12 inch block of poured concrete that is attached to a rock formation on the peak. The disc is hard to read. There is an arrow on the center of the disk with "SOUTH TWIN" above the arrow and "2" below the arrow.
Another benchmark disk is also present here about 6 feet away, but it is in bad condition and almost unreadable.
Being so exposed on this hilltop, conditions were cold and very windy.
