Well, looks like it was really a Turkey Vulture, not a California Condor.
For example, see the condor in the first line art (shown at right) in
See how the tail of the condor is shorter and fan-like? And less bend
(dihedral) in the wing.
For a good picture of the Turkey Vulture, goto http://www.nps.gov/ever/eco/vulture.htm, shown at left:
Also see http://arizonaes.fws.gov/californ.htm for more pictures and descriptions of both the vulture and the condor; the condor is shown below right.
Well, at least it was a big bird, and nobody died on the trail!
