Wave-formed ripple Wave-formed ripple In sedimentology, wave-formed ripples or wave-formed ripple marks are a feature of sediments (sandstones, limestones, siltstones) and dunes. These ripple marks are often characterised (and thus distinguished from current ripples) by symmetric cross sections and long relatively straight crests, which may commonly bifurcate. Commonly, these crests can be truncated by subsequent flows. Their wavelength (periodicity) depends on the sediment grain size, water depth and water-particle orbits in the waves. On tidal flats the pattern of wave-formed ripples may be complicated, as a product of changing depth and wind and tidal runoff directions. Symmetrical ripples are commonly found in
The Crests charted with their first release, "Sweetest One", on Joyce Records. After recording two more singles for Joyce Records, Patricia Vandross left The Crests in 1958 to finish her education. Their next single after "16 Candles" on COED Records was "Six Nights A Week" which hit #28 on the "Billboard" Hot 100 Charts and #17 on the R&B. Their next release "Flower Of Love" was bland compared to other Crests cuts and attained only a six-week run-up to #79. From 1958 to 1960 the group was almost always on the road. In the late 1950s, The Crests performed on several national
