Pilons with permanent (year-around) seep and walkway structure above it. Had to load report from home. Can't load more than one photo to overview or profiles. I'm curious about how well the pilons will continue to function. The area directly behind the pilons appears dark, wet and empty so I suspect soil is washing out between the pilons (from seep water and high tides). Vegetation covers slipping bluff area- can't get a good picture of it especially with late summer/early fall vegetation still covering it. 48.22977 N, 122.53452 W"
