Having written last of Fort Stevens on the south side of the mouth of the Columbia River, the lynchpin of the triad of forts arranged to guard the entrance from the sea from 1865 until 1947, it is time to turn our attention to the north side of the river. First, Fort Canby set up on the headland on the north side of the entrance to the mouth. Even today, a visit by car to the Lewis and Clark Interpretive Center – literally erected upon the aprons of one of Fort Canby’s former battery aprons – takes you winding along a narrow densely forested lane giving you just a taste of the primeval nature of the site.
