If the top is completely flat then a slope pattern with only a narrow range
at the top should work.  Assuming the Ice & White textures are already
defined...

#declare Text_Texture = texture {
  slope
  texture_map {
    [0.00  Ice_Texture ]
    [0.95  Ice_Texture ]
    [0.95  White_Texture ]
    [1.00  White_Texture ]
  }
}
