Perego’s Lagoon is a geological and ocean anomaly along the western shores of Ebey’s Landing National Historic Reserve on Whidbey Island. It is reached by the 3+ mile long Ebey’s Landing bluff loop trail, which goes along the beach, around Perego’s Lagoon, and up & back along the tall bluffs above (or the other way around).
Perego’s Lagoon is formed by a barrier beach with a very shallow lagoon trapped between Puget Sound and the bluffs. Storm-driven driftwood is scattered about. You can walk either along the beach or otherwise on a landward side trail between the main line of driftwood and the lagoon. It adds even more variety to one of the area’s most beautiful hikes.
I hiked the upper and lower trail along these lagoons today and from what I can Severn it appears that at some point in the past geologic history of this area there was a slide event large enough to creat the lagoons.
This may be proved or disproved by examination of sediments in the sound
In front and at the base of the bluff.
Any thoughts
Hi JP,
Although I am not a geologist, I believe it is likely caused by littoral drift of sand sediment accumulating there. Littoral drift, or longshore drift, pushes sediments along the shoreline there from the north by the action of wind, waves, and currents.

I see what you mean but I also considered the arial view, the sediment
Makeup of the slope and ongoing slumping of areas at base.
Large slide events may create these
Type of depressions and I think a good portion of leading edge of the side is below water line and eroded away
By current and wave action.
Just a theory but fun to speculate.
Satellite view is telling
Used to study stereo photos of
Geological formations.
I think there is more about it from
The park service. Going to check it
Out.
Hi JP,
I recommend checking out local expert Hugh Shipman’s blog. He specifically talks about Perego’s Lagoon at http://gravelbeach.blogspot.com/2015/12/peregos-lagoon.html, as well as a huge range of many other local coastal geological features that you may find interesting.
