From Pelly Crossing, mushers travel west on the frozen Pelly River, or on a road that parallels the river if ice conditions are poor. At Stepping Stone, shortly before the Pelly and Yukon rivers meet, they can rest at a hospitality stop before turning north. From Stepping Stone to Scroggie Creek the trail consists of a mining road or "cat" road, named for the Caterpillar tracked mining vehicles that use it. Before organizers coordinated schedules with the mining equipment operators, racers often had to contend with heavy machinery blocking the trail or turning it into a muddy path. The Scroggie Creek dog drop is at the confluence of the Stewart River and Scroggie Creek.
