This trail is a great alternative to the Aspen Creek Trail #48. The split off East Copper Trail #260 is not marked but gets enough use that it's easy to find. If descending Trail #260, Moby splits off just after the first righthand turn.
Starting from East Copper Trail #260, this is beautiful singletrack twisting through a lush Gambel Oak grove. Next comes some gentle climbing through pines before becoming a bit more exposed with some very expansive views. There are a few narrow spots, so watch your line.
About half a mile (maybe less) in, there is an unmarked intersection. Stay left or you'll find yourself on Aspen Creek Trail #48. After about one mile of twisting singletrack, the trail overlays some old abandoned mining/forest roads and the descent steepens. It is a steep downhill until you join the Aspen Creek Trail #48 just above the Copper Basin Road Trailhead.
