Alt Text Area map of the Fort Vancouver National Historic Site in Washington. A ragged-edged, round gray area in the center straddles the state line between Washington and Oregon. Two sites are labeled with green callout boxes, and highways are represented with yellow lines. Extended Description The Columbia River, which also acts as the state line, curves shallowly across the gray area. Vancouver is labeled in Washington and Fort Vancouver National Historic Site is near the intersection of Interstate 5 and the river. Portland is south of the river. The other green callout box identifies McLoughlin House along the southern edge of the ruffle-edged gray area near Interstate 205. Interstate 84 travels east-west in Oregon and connects Interstates 5 and 205. Legend A scale along the bottom of the map measures distances of 25 kilometers and 25 miles.
