Coastal Processes of the Whatcom County Mainland (dnr.wa.gov)
Numerous natural erosional and depositional processes operate upon shorelines to create a diversity of coastal landforms. Waves are among the most important causes of this diversity as they remove, build, and shape beaches and sea cliffs.- Age of Aquarius (Wikipedia)
The Age of Aquarius, in astrology, is either the current or forthcoming astrological age, depending on the method of calculation. Astrologers maintain that an astrological age is a product of the Earth’s slow precessional rotation and lasts for 2,160 years, on average (one Great Year equals 25,920-year period of precession / 12 zodiac signs = 2,160 years).
