"Mountains and Sea", Frankenthaler's first professionally exhibited work, is generally identified as her most well-known painting because of its use of soak stain. The work itself was painted after a trip to Nova Scotia, calling into question just how non-representational the painting is. While "Mountains and Sea" is not a direct depiction of a Nova Scotia coastline, there are elements of it that suggest a kind of seascape or landscape, like the strokes of blue that join with areas of green. Much like "Mountains and Sea", Frankenthaler's "Basque Landscape" (1958) seems to refer to a very specific, external environment, thus it is also abstract. The same can be said for "Lorelei" (1956), a work based on a boat ride Frankenthaler took down the Rhine.
