As you walk along the River Walk next to the trolley tracks, you pass Mill Pond. Most of us know it as an upscale housing development. The houses are new, and new construction continues. Before my time, this round pond was actually part of the old mill, and was surrounded by buildings related to milling wood. There's a very short waterway (only the width of the River Walk and the tracks) that connects the pond with the Columbia River. Each house is unique, and some are actually quite strange in their floor plans, but I'm glad that the codes required a look that makes them compatible with the old Victorians of Astoria. Birds love the pond, and you can always see various species swimming here or roosting on a few pieces of wood sticking out of the water. The hills behind the buildings are a little higher than you see here. On this rainy day, they're obscured by clouds. Mill Pond is the round body of water near the river's edge in this aerial photo.
