Just getting to the trailhead presents the most trouble for some who have tried the Southwest Couloir Route on Granite Peak. I posted this map after being lambasted for poor directions to the trailhead. May this picture be worth a thousand words...

LuLu Pass Road starts 1.8 mi. east of Cooke City and continues north and west to Lulu Pass. The turnoff for the trailhead is just after crossing Fisher Creek at 8800' elevation. Lady of the Lake, your first landmark along the route, is in the upper right corner of this map.
