National Forest Development Road 100 is a cross-country skiing route in Washington's Okanogan-Wenatchee National Forest, within the Methow Valley Ranger District. The Forest Service manages the land, and the route is an out-and-back that covers about 2.7 miles with a total elevation gain and loss of roughly 1,240 feet. The climb is back-loaded, with the steepest stretch at about 0.13 miles from the start. The route begins around 3,520 feet and peaks near 3,535 feet, with the low point at about 3,093 feet. Spring and fall bring the most comfortable conditions. Typical averages from a nearby weather station in Mazama show April highs around 58°F with lows near 33°F, and October highs near 56°F. That station sits about 1,400 feet lower, so temperatures on this route run cooler. Cassal Hut is less than a mile away and West Fawn Creek Road is about 1.4 miles off. For climbers, The Sweet Spot and The Matrix are both within about 2 miles, and Early Winters Campground lies about 5.5 miles away.
