This is a scan of Fort Clatsop National Historic Site just outside of Astoria, OR.
While it is not the 'original' for that the Lewis & Clark Expedition used during their time on the Oregon coast during the winter of 1805-06, it is a very faithful replica, and is a hidden gem in the US National Park Service's many sites.
2 quick combined scans taken with an XGRIDS PortalCam in about 25 minutes total (in order to get as much detail from the foliage as possible).
