Deception Pass is unique in that the tidal flow beneath the twin bridges (built in 1935) connecting Fidalgo Island to Whidbey Island is extremely fast and rough. During lower tides, the swift current can lead to standing waves, huge whirlpools, and roiling eddies. This swift current phenomenon can be viewed from the twin bridges' pedestrian walkways or from the trail leading below the larger south bridge from the parking lot on the Whidbey Island side.
You might have noticed my 1982 Copyright on the image above. This photo was made almost 30 years ago from a point of land beneath the bridge during a photo excursion with a friend. Climbing our way back up the hillside in the dark is a memory I'll always retain ... but over the ensuing years consistent print sales of this image have repaid that arduous trek many times over.

For those who care ... this image was made with a Canon fTb using Kodachrome 25 transparency film and digitally scanned with a Nikon LS-5000 scanner.
I've jumped the gun by a few hours for this Friday photo ... but since it's not current events I guess it's permissible :)
