Observing our Changing Bluffs
Sound Water Stewards have been trained in how to use the MyCoast/WA mobile device app to take pictures and share observations about with the United States Geological Survey (USGS) and Western Washington University’s (WWU) researchers.
The project engages community science volunteers in describing and tracking changes in bluff and beach characteristics over time. This data will allow the USGS to test and calibrate predictive models to create a regional hazard map and advance further models that evaluate present and future bluff vulnerability.
Researchers are particularly interested in pictures and reports of seeps, undercuts and slides (new and old) on the bluffs in Island County and throughout the Salish Sea and Puget Sound.
Project observations are recorded and submitted through “bluff reporter” in the MyCoast/WA app for mobile device.
Sound Water Stewards monitor the sites listed below.
Possession Point, Whidbey
The entire length of this bluff, which extends south, around the point, and back into Cultus Bay, supports a number of active slides. We monitor several of the northernmost slides. Particularly entrancing here are the many layers of ancient peat alternating with other deposits which make rich, fantastical formations in which some see a dragon spine and layer cakes.

Strawberry Point, Whidbey
SWS Science studies with the USGS and Western Washington University to document bluff collapse and subsequent degradation. Bluff erosion is estimated approximately to be about an inch a year.
Metric: 125
Height (in feet) of bluff above sea level.
Barnum Point Preserve, Camano
Tall bluffs here have historic slides with good size slide deposits up to 80 feet in length. Beach is only accessible at mid to low tides. Thanks to Whidbey Camano Land Trust, this large acreage with over 1 mile of beach is now preserved. Previously it contained only 3 or 4 homes. Bluffs here are impacted by south winds during winter storm seasons.
Camano Island State Park, Camano
SOUTH – The 80-100 feet tall bluffs that face south are are actively eroding. They are easily accessible at .3 miles from the south end of the south parking lot below the campground
