Kamus Drive

The wet conditions that led into the winter of 1998-99 must have exceeded some region-wide threshold.  Deep-seated slides reactivated all over Puget Sound, from Olympia to Point Roberts, as well as here on the west side of Fox Island.  At first blush, and perhaps at high tide, this might have looked like a large shallow failure, but low tide revealed that the clay below the tide beach had been raised 10-20 feet in a big arc, marking the toe of a deeper rotational slide.
The initial report that I heard was that a spit-like feature had appeared. When I first saw it - at low tide - the impermable clay ridge had turned the upper beach into large tidepool.

The uplifted clays, although much eroded and/or subsided, still crop out on the beach 13 years later.  The house (
try typing "askew" into Google) remains as it was left.
