As I said, we're looking eastward, upriver. The hills are all in Washington, while the foreground is in Oregon. The white roof at the bottom of the photo is the Maritime Museum. The lump of land sticking way out on the far peninsula is Tongue Point, visible in a number of photos, including this one taken at the Maritime Museum showing the lightship Columbia, which is half visible at the very bottom of the photo.
The first structure towards the viewer from Tongue Point is Pier 39, just at the top of the double basins made from jetties that create East Mooring Basin. Pier 39 appeared in a number of posts: Pier 39, the kayak place, and Bumblebee Seafoods. Showing East Mooring Basin itself are several other posts, including this pink sunset with fishing boats, my sea lion post, and this photo from last May.
Moving closer again to the viewer, the big red building sticks out into the water all on its own. Here's a photo of it from July. The River Walk runs the entire length of the river's shore here (and much further "down"). In fact, most of the downtown area is below the bottom of this picture. In the middle of the long stretch of River Walk, you see a round pool in the land area. This is called Mill Pond, and I don't have any photos yet. It connects to the Columbia River via a very short waterway, and in the past it was actually the pond for a large lumber mill. Now there are new houses surrounding the pond, and some are built on stilts over the pond's edge. The water birds enjoy the pond, and I'll try and take some interesting photos before long.
