In case anyone wanted to try this at home, there's a typo above.  What I literally
did was this:

#declare fnoise=.05;
#declare  MyObject=
isosurface{
          function{y/290+
                  noise3d(x*fnoise,y*fnoise,z*fnoise)/1
                  }
           accuracy 0.01
           threshold .21
           contained_by {
                      sphere{0,100}
                        }
        pigment{SeaGreen}
        finish{ambient 0.1}

        }
