Steve's post starts at LeConte, but Dixon actually describes the route as beginning at the South Lake TH. Starting at LeConte, then it looks like five crosses: Junction Pass, Shepherd Pass, Russell-Carillon, Mountaineers Route and Army. Maybe he's counting tagging a peak at the crest as crossing it over and back.
It looks like a great route, in any case, and much of it I have planned to use in my John Muir Route next summer.
