That tiny white plume is the Port Townsend Paper Mill. Although it’s a bit over 2.5 miles from where I took the photo, the mill isn’t really that small in person – it appears that way in this image because I used a wide camera angle¹. Which also explains the weird-looking dock pilings.
¹28mm in 35mm equivalent.
