Given an effective action of an (n-1)-dimensional torus on an n-dimensional
normal affine variety, Mumford constructs a toroidal embedding, while Altmann
and Hausen give a description in terms of a polyhedral divisor on a curve. We
compare the fan of the toroidal embedding with this polyhedral divisor.
