Hmmmmm. Either my previous answer wasn't what you wanted to do, not working
right for you, or you somehow missed reading it? I noticed someone else (oh,
was Bonsai in p.b.s-f.) also answered similar as me. Anyway, here is that
again:

"You'll need to intersect or difference a box and the HF since they
are only a one unit square with an implied depth."

intersection {
    height_field {...} // could texture this here
    box {0,1} // could texture this here
// or both here
}

As long as you don't change the scale or move the HF before this is done you
should get a box shape for the lower portion. If you were to difference the
two, instead, you would need to add 'inverse' to the box for it to retain
the HF area.

I don't remember how earlier versions dealt with the HF shape. If this isn't
going right for you please ask for more help.
