During World War II a Lower Mainland Defense System was built to protect the port of Vancouver from enemy raids. Between Point Atkinson (North) and Point Grey (South) ran an imaginary line called the examination line. This marked off the harbour, all ship traffic beyond this point had to be inspected and authorized. There was a gun battery at Point Atkinson and also at Point Grey where the Museum of Anthropology now stands. The barracks that used to house the gunners at Point Atkinson are still there and are now part of Lighthouse Park. The images I took below shows the battery overlooking the Narrows which was built in 1942. As I hiked back to my vehicle I heard the distinct call of a Barred owl. It was a nice evening to be outside exploring with my camera.
