Diaper Line is a cross-country skiing route in the Bozeman Ranger District of Custer Gallatin National Forest in Montana, managed by the Forest Service. The out-and-back trip covers about 8.5 miles, with a one-way climb of 902 feet from a low point of 5,845 feet to a high of 6,673 feet. The steepest stretch comes at about 3.2 miles in, with a 13% grade. Winter is the natural season for this route. Typical averages from a nearby weather station at Big Sky show January highs around 30°F with lows near 9°F, while July highs reach about 78°F. That station sits at a similar elevation to the route, so its figures are a fair guide to conditions here. The route starts close to several other destinations. The Fr 3159 junction of Moser Rd 6210 and 6212 is about 0.1 mile away, and the South Diaper Line hike is about 0.5 mile off. Climbers can head to Crocodile Rock, about 1.6 miles away, and the Bozeman District lake fishing area is about 9.4 miles away.
