Hi Kmc,
Route from GPS from Sept. 2012 can be found at:
MR gps route This route goes up the MR, and down the main trail. Also, gps went a bit "wonky" going up the final 400 (fairly normal I guess), but you will see the way I think.
This is a "live" map, that you can pan, zoom, etc... Also, for best results use the pull down (upper right), and select t4 topo high. This is most detailed map.
There were a couple of "off route" excursions, but nothing serious. Many use trails and water runoff paths that look inviting.
Good luck.
John
