Fort Stevens sits right on the mouth of the Columbia. It sits on the south side of the river, while Fort Canby, another military base from the same time period, sits on the north side of the river in Washington. The south jetty is at the northern-most end of the park and extends 2 miles out. It was built to help create calm waters in order for the ships to safely leave the ocean and move into the river.
Hopefully tomorrow . . . final edition!
