  We show that, in the first or second order orthonormal frame formalism, black
hole entropy is the horizon Noether charge for a combination of diffeomorphism
and local Lorentz symmetry involving the Lie derivative of the frame. The
Noether charge for diffeomorphisms alone is unsuitable, since a regular frame
cannot be invariant under the flow of the Killing field at the bifurcation
surface. We apply this formalism to Lagrangians polynomial in wedge products of
the frame field 1-form and curvature 2-form, including general relativity,
Lovelock gravity, and "topological" terms in four dimensions.
