Bird Blind (2008) at the Sandy River - Columbia confluence, designed by Maya Lin. 
Locally harvested black locust tree (an invasive specie) and steel. Elegant and simple design. The gently curved walkway almost melts into the background. Each vertical plank is engraved with a note on local plant/animal found during Lewis and Clark expedition. 
One minor drawback is that the Sandy River project is in a dog park (Lewis Clark State Park), where the dogs are running free (despite the signs for mandatory leash on the Confluence trail and around the blind). One of us met her friends, the owner husband and wife of Grand Central bakery, who, instead of apologize for not putting their dog on leash, started immediately criticizing the inadequacy of the signs). Like half of others we encountered at the flat park, put their dogs on leash when asked to. Half completely ignored the request.Pluses are: lots of stinging nettle in the woods. I picked some and later boiled to eat. Little silvery fish in the water: salmon smolt? View of river and Mt. Hood.
Vancouver Land Bridge (2008) by Johnpaul Jones, which connects Columbia River front to Fort Vancouver, over Hwy 14. 
Native plants (with labels indicating their use) line both sides of the curvy walkway. Cast iron fence and roof provide interesting shadows. Resting stops decorated with native American tribal names and iron pictographs. Even the water drain is artfully designed. A Welcome Gate, designed by Native American artist Lillian Pitt. An old apple tree (probably nothing to do with the project). 
We spent over an hour checking out the historical Fort. Chatted with one lady who rents in one of the stately houses on Officers Row - available for residential, commercial or event rental. A nice restaurant, Windermere, Vancouver Business Journal, Columbia Land Trust. Magnolia trees are in full bloom here. Tall sequoia, big manicured lawn. Quite lovely. Most of the old barracks are vacant, in need of proper maintenance. Only 2 small parts are occupied: a barber shop and a packaging office.
