With increasing p_T, the away-side distribution evolves from a broad to a concave shape, then to a convex shape. Comparisons to p+p data suggest that the away-side can be divided into a partially suppressed \"head\" region centered at Delta\\phi ~ \\pi, and an enhanced \"shoulder\" region centered at Delta\\phi ~ \\pi +/- 1.1. The p_T spectrum for the \"head\" region softens toward central collisions, consistent with the onset of jet quenching.
