Zig Zag border and Oak Hill

The reward of most climbs is the view and this walk provides a fine vista over Gungahlin. The sign below is on the northern border and shows a trig station on the hill.

Why is this interesting?

Percy Sheaffe and his team surveyed this portion of the border in May 1911. The borderline, as seen in the images above, is marked by a star picket fence of wire mesh and two upper strands of barbed wire. The zigzag nature of this section of the border along the crests of the hills was specifically designed to capture watershed for the ACT.
